radiation physics-exam 2 review

What is the difference between series and parallel circuits?

Series = electrons have one way

Parallel = has a bunch of ways

What is potential difference?

The difference of electrons from one point to another

What is the current?

How many electrons flow per second

What is resistance?

Anything that hinders the flow

What is the difference between direct and alternating current?

Alternating current has negative and positive swings

Direct has only positive

What are material materials called when they are strongly attracted to a magnet?

Ferromagnetic material

What is the difference between a solenoid and an electromagnet?

Electromagnet has a core

What is the power equation?

P=iV
