Electricity

Question 1

Static electricity

Answer 1

Is a build up of electric charge that can occur on good insulators e.g. polythene and Perspex rods

Question 2

Polythene rod

Answer 2

Gains electrons if a woollen cloth is rubbed on it (becomes negatively charged)

Question 3

Perspex rod

Answer 3

Loses electrons if it is rubbed by a woollen cloth (becomes positively charged)

Question 4

High electrical pressure

Answer 4

The negative end of a battery

Question 5

Low electrical pressure

Answer 5

The positive end of a battery

Question 6

Potential difference

Answer 6

The difference in electrical pressure between the positive and negative ends

Question 7

Voltage

Answer 7

This is what the potential difference is known as and is measured in volts

Question 8

Resistance

Answer 8

Is the opposition to the flow of electrons. The unit is the Ohm (insert omega sign), and it is measured using an Ohmmeter

Question 9

Resistor

Answer 9

If this is placed in an electric circuit, it will slow down the flow of electrons
