In the circuit shown in Fig. currrent through the battery at `t = 0` and `t = oo` is

Options

A. `1.5 A, 1.5 A`
B. `0,0`
C. `1 A, 1.5 A`
D. `1.5 A, 0 `

Answer

A

Explanation

In Fig. at `t = 0`, current will flow from the capacitor ans at `t = oo`, inductor provides the path of zero resistance to the flow of current. Therefore, in each case, current through battery.
`I = (V)/(R ) = (15 V)/(10 Omega) = 1.5 A`
