Heating in Circuits Flashcards

All 3 cards in this deck

When there is a current in a resistor, what happens to the resistor?

There is an energy transfer which heats the resistor.

Why does a resistor heat up when there is a current in it (in terms of particles)?

Electrons collide with the ions in the metal lattice, transferring energy to the ions and making them vibrate more.

What happens to the electrical energy when a current does work against electrical resistance?

It is dissipated as thermal energy in the surroundings.
