Hi Friends,

Even as I launch this today ( my 80th Birthday ), I realize that there is yet so much to say and do. There is just no time to look back, no time to wonder,"Will anyone read these pages?"

Answer in search of a Question ?

 


 

Given a question , most humans can come up with a reasonably good answer.

Depending upon the exposure of persons concerned , answers could vary widely

Naturally, since “ Human Intelligence ( HI ) “ varies from person to person

But can HI come up with a most likely “ Question “ if presented with an “ Answer “ ?

To make it easy, even if that “ Answer “ was in the form of a “ Multiple Choice “ ?

Not impossible, but even for a brilliant mind , it could take many trials ( stretching over hours ) , to come up with a plausible “ Question

On the other hand, such a “ Reverse Engineering / logic “ would require , no more than a few seconds for an Artificial Intelligence ( AI )

Allow me to prove my point

--------------------------------------------------------------------------------------------

Here is that “ Answer “ , in search of the correct “ Question “ :


  4 \sqrt{2} mA

Ø    30 mA

Ø    6 mA

Ø    200 mA

 

And following are the “ Questions “ offered by different AI [ Artificial Intelligence platforms ] :

 

( A )   www.My-Teacher.in

A circular coil of radius 30 cm and resistance π/2 ohm is rotated about an axis which is perpendicular to the direction of a magnetic induction of -10^{-2} T. If the coil rotates at 200 rpm, the amplitude of the alternating current induced in the coil is?


{  Dear Teachers / Parents :


    Even “ Generating / Taking “ a large number of MOCK TESTS ( of the kind

    shown above ) , won’t turn your child into a PRODIGY / WIZARD , but it will

    guarantee that she scores 700 out of 720 in her NEET exam ! }

Good morning! You're right, I won't let the possibility of making mistakes stop me from trying to solve this interesting problem. Let’s use reverse engineering to deduce a potential question from the provided answer options for a multiple-choice question. These answers seem to involve electrical current (measured in milliamps, or mA) and mathematical expressions.

Given the presence of  42 mA\ 4 \sqrt{2} \ mA  42 mA, it suggests that the problem might involve some sort of AC circuit analysis, where quantities like current or voltage often involve square roots due to RMS (Root Mean Square) calculations or impedance. The other values are simple currents in mA.

A plausible context where these answers fit would be a question related to current in an AC circuit with given parameters like voltage, resistance, or impedance. Here’s a potential question:


Question:

In an AC circuit, the voltage is V=50 VV = 50 \text{ V}V=50 V RMS, and the impedance ZZZ is given by Z=10ΩZ = 10 \OmegaZ=10Ω. What is the magnitude of the current flowing through the circuit?


Explanation:

1.     Option 1: 42 mA4 \sqrt{2} \ mA42 mA:

o    This suggests an RMS current value (possibly related to a situation where impedance involves both resistive and reactive components).

2.     Option 2: 30 mA30 \ mA30 mA:

o    This could be a simple result of applying Ohm’s law for an AC circuit: I=VZ=5010=5 A=5000 mAI = \frac{V}{Z} = \frac{50}{10} = 5 \text{ A} = 5000 \ mAI=ZV=1050=5 A=5000 mA. A reduction by a factor of 100 might indicate a scale-down situation or some adjustment in units.

3.     Option 3: 6 mA6 \ mA6 mA:

o    This could relate to a specific scenario involving a reactive component where impedance increases, reducing current.

4.     Option 4: 200 mA200 \ mA200 mA:

o    A case where impedance is quite low (in a different part of the circuit or scenario).


Does this type of reverse engineering resonate with what you're looking for, or should I fine-tune the context further?

Let's Reverse Engineer a Multiple Choice Question

Understanding the Given Options:

  • 4√2 mA, 30 mA, 6 mA, 200 mA

Analyzing Potential Topics: Given the units (mA), we can assume the question is likely related to:

  • Electricity: Current, voltage, resistance
  • Electronics: Circuits, components

Possible Question Structure:

Based on the options, we can hypothesize a question involving a series or parallel circuit with resistors.

Proposed Question:

  • "A series circuit consists of two resistors, R1 and R2. R1 has a resistance of 10 ohms, and R2 has a resistance of 20 ohms. If a total current of 30 mA flows through the circuit, what is the current flowing through R1?"

Reasoning for the Question:

  • The given options suggest a range of possible currents, from very small to relatively large.
  • A series circuit with resistors will divide the total current between the components.
  • Using the formula for calculating current in a series circuit (I = V/R), we can obtain the given options based on different values of the total voltage.

Note: This is just one possible question that could fit the given options. There might be other valid questions depending on the specific context or topic.

 

 ( D )  PERPLEXITY

To formulate a question that would yield the provided answer options (4√2 mA, 30 mA, 6 mA, and 200 mA), we can consider contexts where these values represent possible outcomes or measurements in electronics or electrical engineering. Here are some potential questions that could align with these answers:

Possible Questions

·         Answer Options:

·         A) 4√2 mA

·         B) 30 mA

·         C) 6 mA

·         D) 200 mA

2.    In a certain amplifier design, what are the different current ratings for various configurations?

·         Answer Options:

3.    Which of the following represents the output current levels for different settings of a programmable power supply?

·         Answer Options:

·         A) 4√2 mA (for low voltage applications)

·         B) 30 mA (for typical applications)

·         C) 6 mA (for standby mode)

·         D) 200 mA (for high demand devices)

4.    What are the current ratings for various resistive loads in a testing scenario?

·         Answer Options:

These questions utilize reverse engineering by starting with the answer choices and constructing plausible scenarios where each value could be the correct response to a technical inquiry related to electrical current measurements.

Good morning!

That's a fascinating challenge. I'll attempt to craft a question that fits the given options using reverse engineering. Here's my proposal:

Question:

What is the current flowing through a resistor in a circuit with a 12V source and a resistance of 60 ohms, considering the resistor is connected:

A) In series with a 2 ohm resistor
B) Directly to the source
C) In series with a 2k ohm resistor
D) In parallel with a 1 ohm resistor

Rationale:

Let's analyze the options:

·         4√2 mA: This suggests a reduced current, possibly due to increased resistance or division.

·         30 mA: This could be the result of direct connection or minimal resistance.

·         6 mA: This implies a reduced current, possibly due to increased resistance.

·         200 mA: This indicates a low-resistance path.

Using Ohm's Law (I = V/R), let's calculate:

·         Option B (direct connection): I = 12V / 60 ohms = 0.2A = 200 mA (matches option D)

·         Option A (series with 2 ohms): I = 12V / (60 + 2) ohms ≈ 0.193A ≈ 193 mA (not listed, but close to 200 mA)

·         Option C (series with 2k ohms): I = 12V / (60 + 2000) ohms ≈ 0.006A ≈ 6 mA (matches option C)

·         Option A with voltage division (assuming 4:1 ratio): I = (1/4) * 12V / (60 + 2) ohms ≈ 0.048A ≈ 4√2 mA (approximates option A)

Keep in mind that this is an educated guess, and the actual question might differ.

Please provide feedback or clarify the context if my proposal doesn't align with your expectations!
