The equivalent resistance of the circuit shown below between points a and b is :

JEE Main 2023 (Online) 10th April Morning Shift Physics - Current Electricity Question 68 English

Accepted Answer

Rearranging the above circuit we get

JEE Main 2023 (Online) 10th April Morning Shift Physics - Current Electricity Question 68 English Explanation 2

The above circuit is a balanced wheatstone bridge there is no current in the branch

c d

.

So we have two

8 \Omega

and one

16 \Omega

resistor in parallel. If

R_{\mathrm{eq}}

is equivalent resistance, then

\begin{aligned}&amp;\frac{1}{R_{\mathrm{eq}}}=\frac{1}{8}+\frac{1}{8}+\frac{1}{16}=\frac{5}{16} \\\\&amp;\Rightarrow R_{\mathrm{eq}}=\frac{16}{5}=3.2 \Omega\end{aligned}
