The question before or after this one on your homework has something to do with airplanes. These answer choices belong with that airplane question. They're not the choices for the snowy-car question. None of them is the correct answer.

You'll want to look for a set of choices that might include "conduction" or "convection".

Explain what makes up a circuit .
ANEK [815]

Explanation:

An electrical circuit needs:

a source of electrical power (this could be a power plant or a battery)

a material along which the electricity can flow (this may be a copper wire)

something to power (this could be a bulb)

The circuit is connected in a loop. Then, the source of power pushes electrons around the wire. It lights the bulb and continues in the circuit until it is broken.

A simple circuit lights one bulb. More difficult circuits might have several switches and loops. This would allow different groups of lights to be turned on or off at the same time.

( I hope this was helpful) >;D
