Find the power of the circuit                                     [AIEEE 2002]

A)            1.5 W                                       

B)            2 W

C)            1 W                                          

D)            None of these

Correct Answer: C

Solution :

                   In steady state the branch containing capacitors, can be neglected. So reduced circuit is as follows  Power \[P=\frac{{{V}^{2}}}{R}=\frac{{{(2)}^{2}}}{4}=1\,W\].
