The type of current that is typically found in household outlets
What is alternating current (AC)?
A disadvantage of this circuit is that all loads go out if one goes out
What is a series circuit
The build up of electrons on an object
What is static electricity?
If a circuit has 10 V and a load with a resistance of 5 Ohms what is the current?
What is 2 A
