Question

In the shown figure, find the potential drop across $4\mu F$ capacitor and $6\Omega$ resistor (at steady state)

• A. $0,0$
• B. $0,3V$
• C. $0,2V$
• D. $2V,0$

Answer 1

The correct option is D $2V,0$

$I=\frac{3}{2+4}=\frac{1}{2}A$

Potential drop across $4\Omega$ resistor is $V=4\times \frac{1}{2}=2V$

The whole potential drop occurs across $4\mu F$ capacitor as current does not exist in the branch containing capacitor.
Hence the drop across $6\Omega$ resistor is zero.
