5.6B Electricity Fast Focus

Front

What happens in a simple series circuit when the switch is opened?

Back

Opening the switch breaks the closed circuit.

Front

In a circuit diagram, which wires can be removed without breaking the circuit?

Back

Wires that are not part of the closed loop can be removed without breaking the circuit.

Front

What is a good insulator of electricity?

Back

Plastic is a good insulator of electricity.

Front

Why might a lightbulb in a circuit not work?

Back

The lightbulb may not work if the wires are connected incorrectly.

Front

What type of circuit allows electric current to have more than one path to follow?

Back

A parallel circuit allows electric current to have more than one path.

Front

Define a series circuit.

Back

A series circuit is a circuit in which the components are connected end-to-end, so that the current flows through each component in turn.

Front

Define a parallel circuit.

Back

A parallel circuit is a circuit in which the components are connected across common points or junctions, providing multiple paths for the current.

Front

What is the role of a switch in an electrical circuit?

Back

A switch controls the flow of electricity by opening or closing the circuit.

Front

What is the effect of adding more resistors in a series circuit?

Back

Adding more resistors in a series circuit increases the total resistance and decreases the current.

Front

What is the effect of adding more resistors in a parallel circuit?

Back

Adding more resistors in a parallel circuit decreases the total resistance and increases the current.
