100
Good conductors have low _______.
What is resistance?
200
This is the loss of static electricity as charges move off an object.
What is electric discharge?
200
Materials with a resistance of 0 (ohms) is called this.

300
Electrons that move from one object to another through direct contact.
What is conduction?
300
The size of the current depends on this.
What is voltage?
300
This is the rate that electrical energy is changed into other forms of energy.
What is electric power?
300
This is the switch that opens if the current is too high.
