This podcast episode on electrical circuits is a class recording. In it, Bryan discusses transformers, ground, common, and line vs. load sides of a circuit.

Transformers use induction to pass alternating current signals to electrical appliances. Alternating currents (AC circuits) are tricky because the current switches direction each time. Therefore, the current flow is difficult to visualize because the direction keeps changing. Electrons naturally want to go to the other side of the transformer, not to ground. So, we have to connect both sides of the transformer to ground to send electrons…
