Question 53 of 380

In the given circuit, the current in resistance ${R}_{3}$ is:

A$1A$B$1.5A$C$2A$D$2.5A$

Show answer and solution▾

Answer: (A) $1A$

Equivalent resistance, ${R}_{eq}=2\Omega +\dfrac{4\times 4}{4+4}\Omega +1\Omega =5\Omega$
Current through battery, $i=\dfrac{V}{{R}_{eq}}=\dfrac{10}{5}=2A$
Current in resistance ${R}_{3}=2\times \left(\dfrac{4}{4+4}\right)$
$=2\times \dfrac{4}{8}$
$=1A$
