Equivalent resistance between A and B will be

• A: 2 ohm
• B: 18 ohm
• C: 6 ohm
• D: 3.6 ohm

To find the equivalent resistance between points A and B in a circuit, we need to know how the resistors are connected—whether in series or parallel. However, without a specific circuit diagram, I can provide a general approach for both configurations.

Resistors in Series

When resistors are connected in series, the total or equivalent resistance (R_eq) is simply the sum of the individual resistances:

• R_eq = R₁ + R₂ + R₃ + ...

Resistors in Parallel

For resistors in parallel, the formula for equivalent resistance is:

• 1/R_eq = 1/R₁ + 1/R₂ + 1/R₃ + ...

Example Calculation

If we assume the resistors A (2 ohms), B (18 ohms), C (6 ohms), and D (3.6 ohms) are connected in a specific way, we can calculate the equivalent resistance accordingly. Here’s a quick example:

Series Example

If A, B, C, and D are in series:

R_eq = 2 + 18 + 6 + 3.6 = 29.6 ohms

Parallel Example

If A, B, C, and D are in parallel:

1/R_eq = 1/2 + 1/18 + 1/6 + 1/3.6

Calculating this gives:

1/R_eq ≈ 0.5 + 0.0556 + 0.1667 + 0.2778 ≈ 0.9991

Thus, R_eq ≈ 1 ohm.

To determine the exact equivalent resistance, please clarify how the resistors are connected in your circuit.
