At t =0s, the current in the circuit in the figure is i0. at what time is the current 12i0?
ipn [44]

When the current is time-dependent, the circuit has a capacitor. A capacitor could be used to store energy. As you use it up, the energy depletes. This is why it is time-dependent. The answer is 12 seconds. I hope I answered your question. Have a good day and thanks.
