Electricity

Question 1

What is static electricity?

Answer 1

a build up of charge in one place
e.g. baloon and hair

Question 2

What is current elctricity?

Answer 2

Flow of charge from one place to another
e.g. turning on a light

Question 3

What is an electrical conductor?

Answer 3

Any object that easily allows charge to flow along it
e.g. metal

Question 4

What is an electrical insulator?

Answer 4

Any object that resists the flow of charge along it
e.g. plastic

Question 5

What is voltage?

Answer 5

The force moving charge around the circuit

Question 6

What is current?

Answer 6

The amount of charge flowing past any point in a circuit

Question 7

What is resistance?

Answer 7

The characteristic of the materials in the circuit that opposes flow of charge

Question 8

What does Ohm’s Law state?

Answer 8

At a constant temperature, the amount of current passing through a material is directly proportional to the voltage across it.
The greater the voltage, the greater the current
