Electronic music is older than you may think. Enter the theremin - a device that turns your body into part of a capacitor, and allows you to play music without even touching an instrument!

We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or Alternating Currents). We’ve talked about how they change voltage, which helps transmit electricity over long distances, but there’s so much...

Find the energy stored in the capacitor and the inductor at steady-state

Before t = 0, S1 was closed and S2 was opened, both for a long time. At t = 0, both switches were flipped. Find the current i(t) after t = 0.

The switch was OPEN for a long time before t = 0. At time t = 0, the switch is closed. What is the voltage VAB at time t = 0+? What is IL(t) at time t = 1 ms?

The switch was closed for a long time before t = 0. At time t = 0, the switch is opened. 1. Determine the energy that was stored in the inductor at time t = 0- (i.e., when the switch was still closed) 2. Determine the voltage V5k across...
