Circuits and Electricity

Front

As resistors are added in series to a circuit, what happens to the total resistance?

Back

The total resistance will increase.

Front

What is a PATH along which electricity can flow?

Back

A circuit.

Front

As the resistance of a circuit increases, what happens to the current?

Back

The current will decrease.

Front

What is a material that resists, or does NOT allow, energy to flow through?

Back

An insulator.

Front

What happens if the switch in a circuit is opened?

Back

The light bulbs would not work because the path was broken.

Front

What is the role of a conductor in a circuit?

Back

A conductor allows electricity to flow through it.

Front

What is the difference between series and parallel circuits?

Back

In a series circuit, components are connected end-to-end, while in a parallel circuit, components are connected across common points.

Front

What is voltage?

Back

Voltage is the electrical potential difference between two points in a circuit.

Front

What is the unit of resistance?

Back

The unit of resistance is the ohm (Ω).

Front

What happens to the total current in a parallel circuit when more branches are added?

Back

The total current increases.
