Electrical components, like motors close motorA device which spins when current flows through it. Motors are used in fans, food processors and many other devices. and lamps close lampA component which ...

The two resistors have the same current through them. The potential difference across them will be different if they have different resistances. The total resistance (\(R_{T}\)) for this circuit is ...

Why don't your Christmas lights work? Sadly, in the event of a string of lights going out on your tree, replacing the strand is usually the best option. It's pretty difficult to find that one bulb ...
