For t ge 0 the voltage across a 1-muf capacitor is vct 10

Question

1. For t ≥ 0 the voltage across a 1-μF capacitor is v_C(t) = 10 u (t) V. Derive expressions for i_C(t) and p(t) . Is the capacitor absorbing power, delivering power, or both?

2. For t ≥ 0 the voltage across a 0:022-μF capacitor is v_C(t) = 5 e^-100t u (t) V. Derive expressions for i_C(t) and p_C(t). Is the capacitor absorbing power, delivering power, or both?
