Electricity Learning Task

An Ammeter is used to measure:

• Electrical energy

• Resistance

• Voltage

• Electric current

The voltage in an electric circuit is a measure of:

• The amount of electric charge passing through a circuit every second

• The amount of electrical energy transformed each second

• The amount of electrical energy gained or lost by electric charge as it moves through a circuit

• The electric current travelling through the circuit

Which of the following represents a typical 'load' in an electric circuit?

• A battery

• A globe

• A wire

• A switch

The flow of electric charge in an electric circuit is called:

• Electric current

• Electric power

• Resistance

• Voltage

If a 6-volt cell is supplied to a globe that is found to use 2-amp, the resistance of the globe is:

• 0.33 ohms

• 3 ohms

• 0.5 ohms

• 12ohms

Conventional current flows from

• Positive to negative

• Negative to positive

If a filament in light K shown in the circuit diagram below breaks:

• Globes J and L will both stop glowing

• Globes J and L will continue to glow

• Globe J will stop glowing and L will continue to glow

• Globe L will stop glowing and J will continue to glow
