A constant(dc) current i(t)=3mA flows into a 50x10^(-6) capacitor. The voltage at t=0 is v(0)= -20V. The references for v(t) and i(t) have the passive configuration.
1. find the power at t=0
2. state whether the power flow into or out of the capacitor at t=0
3. find the power at t=1s
4. state whether the power flows into or out of the capaciotr at t=1s
