What is the definition of current?

• The rate of flow of charge
• The rate of flow of electrons
• The rate of flow of current
• The rate of flow of resistance

Which of the following cannot provide a potential difference?

• A battery
• A power pack
• Mains electricity
• A resistor

In the water model of an electric circuit, the source of potential difference is represented by....

• the pipes
• the water
• the pump
• the water wheel

The equation for current is...

• Current = charge / time
• current = charge x time
• current = potential difference / time
• current = potential difference x time

Current is measured in....

• Amps 
• Volts
• Ohms
• Coulombs

Potential difference is also known as....

• voltage
• current
• resistance 
• volts

1 Amp is the same as....

• 1 Coulomb of charge flowing for 1 second
• 1 Coulomb of charge flowing for 1 minute
• 1 Volt of charge flowing for 1 second
• 1 Volt of charge flowing for 1 minute

Resistance is a measure of....

• the energy per unit charge in a circuit
• how hard it is for electrons to move through the circuit
• how hard it is for electrons to move through the battery
• the number of charge carriers in a circuit
