Question

Find the equivalent resistance across the terminals of source of e.m.f $24V$ for the circuit shown in figure

• A. $15\Omega$
• B. $10\Omega$
• C. $5\Omega$
• D. $4\Omega$

Answer 1

Answer: (C)

$5\Omega$

Given the circuit can be reduced to a simple circuit as shown in figure below

i.e.

Two resistance $\left(10\Omega \right)$ are in parallel connection,

$R_{eq}=\frac{1}{\frac{1}{10}+\frac{1}{10}}=5\Omega$
