Question

In the given circuit the steady state current is?

• A. Zero
• B. $0.6\text{A}$
• C. $0.9\text{A}$
• D. $1.5\text{A}$

Answer 1

The correct option is D $1.5\text{A}$

At the steady state, capacitor works as an open circuit.

$\Rightarrow 2\Omega \&3\Omega$ are in parallel and in series with $2.8\Omega$ resistance.

Now the equivalent resistance of circuit is,

$\Rightarrow R_{\text{eq}}=\frac{2\times 3}{2+3}+2.8=4\Omega$

By Ohm's law $V=IR$, we get current $I$ as,

$I=\frac{6}{4}=1.5\text{A}$
