Question

the resistors in the following image combine to create:
r2 = 15 ohms
r3 = 25 ohms
e_{t}=100v
9.27 ohms
9.03 ohms
9.60 ohms
9.38 ohms

Explanation:

Step1: Calculate the equivalent resistance of \(R_2\) and \(R_3\) in parallel

The formula for parallel resistors is \(R_{eq}=\frac{R_2\times R_3}{R_2 + R_3}\).
Substitute \(R_2 = 15\Omega\) and \(R_3=25\Omega\) into the formula:
\(R_{eq}=\frac{15\times25}{15 + 25}=\frac{375}{40}=9.375\Omega\approx9.38\Omega\)

Answer:

9.38 ohms
