1
Q
What is current?
A
It is the rate of flow of electric charge
2
Q

A
Amps
4
Q
When a voltage is applied, what end do the electrons move to?

It goes from negative to positive
5
Q
What is the main difference between conductors and insulators?
A
Insulated have less free electrons
6
Q
What is potential difference?
A
It is another word for voltage. The difference in work done by or on a charge between two points in the circuit.
7
Q
How is an ammeter connected in a circuit
A
In series (within the loop)
8
Q
How is a voltmeter connected in a circuit?
A
Parallel to the component being measured
