Electricity

Question 1

Current

Answer 1

Ampere (A)

Question 2

Current

Answer 2

Ampere (A)

Question 3

Charge

Answer 3

Coulomb (C)

Question 4

Energy

Answer 4

Joule (J)

Question 5

Voltage

Answer 5

= Current × Resistance

V = I × R

Question 6

Charge

Answer 6

Current × time

Q = I × t

Question 7

What is an electric current?

Answer 7

An electric current is a flow of electrons through wires and components. The electrons have a negative charge and are pulled toward the positive end of the battery.

Question 8

measuring current

Answer 8

Electric current is measured in amps (A) using an ammeter connected in series in the circuit

Question 9

measuring voltage

Answer 9

The ‘electrical push’ which the cell gives to the current is called the voltage. It is measured in volts (V) on a voltmeter

Question 10

parallel circuit

Answer 10

voltage is the same in all parts of the circuit.

Question 11

Charge

Answer 11

Coulomb (C)

Question 12

Energy

Answer 12

Joule (J)

Question 13

Voltage

Answer 13

= Current × Resistance

V = I × R

Question 14

Charge

Answer 14

Current × time

Q = I × t

Question 15
