A ___conductor allows current to flow easily.
2 An insulator does NOT allow current to flow easily.
3 When electrons are pushed from one atom to another, electric current is created.
4 A battery is a source of power. It provides an electrical "pressure".
5 An alternator is a source of power.
6 Voltage is measured in
7 Current is measured in
8 Resistance is measured in
9 Voltage measured across a light bulb is called
10 A circuit in which the electric current goes to ground or to power (another part of the circuit) is called a . Usually this produces a lot of heat, blows fuses, and
trips circuit breakers.
11 A circuit in which the electric current cannot complete the path of the circuit, usually from a break
in a wire, is called an . This causes everything in the circuit to stop working.
12 To protect against too much current flowing through a circuit, the circuit may have a , a , or a .
