Question

The equivalent resistance between A and B is:

• A. \(18\Omega\)
• B. \(25\Omega\)
• C. \(27\Omega\)
• D. \(19\Omega\)

Answer 1

The Correct Option is D

Given the following resistor network, the resistances are arranged as shown:

From the given circuit:

The resistances between points A, B, C, and D are:

\( 6 \, \Omega \) between A and C, \( 10 \, \Omega \) between B and C, \( 8 \, \Omega \) between C and D, \( 5 \, \Omega \) between B and D, and \( 4 \, \Omega \) between A and D.

First, combine the resistances in parallel and series:

Combine the \( 15 \, \Omega \) resistors in series between points A, C, and B. After the simplification, we get:

\( R_{\text{eq}} = 6 \, \Omega + 5 \, \Omega + 8 \, \Omega = 19 \, \Omega \)

Thus, the correct answer is:

\( R_{\text{eq}} = 19 \, \Omega \)

Answer 2

Thus the correct answer is 19 $\Omega$.
