Superconductivity is an advantageous property observed in some materials, which entails an electrical resistance of zero at ...

The increasing use of integrated circuits in modern ... used on single-phase AC supply lines to protect electronic equipment from damage by lightning overvoltages. However, an obvious drawback can be ...

However, this rarely happens and only in AC circuits containing pure resistances. Most AC circuits contain some type of inductance, in which case the current waveform lags the voltage or reaches its ...

But first, we need you to sign in to PBS using one of the services below. We've talked about AC Circuits, but now it's time to delve into the world of AC Circuits (or Alternating Currents).
