A student uses an ammeter to measure the current in a lamp.
Describe how the ammeter must be connected to measure the current in the lamp.
State what is meant by an electric current.
The current in the lamp is 0.50 A.
State the equation linking charge, current and time.
Calculate the charge that flows through the lamp in 120 s.
Give the unit of your answer.
Name the particles that flow through the metal wires of the circuit.
