SNC1L Electricity Test

Electric current will flow only in an open circuit.

• True

• False

Electric current flows more easily through an insulator than a conductor.

• True

• False

An ammeter measures the voltage (potential difference) across a component of a circuit.

• True

• False

Electric current flows more easily through a metal wire than a ruler (plastic).

• True

• False

The four parts of a working electric circuit are the source, the battery, the conductor, and the switch.

• True

• False

The basic purpose of an electric circuit is to create electric energy and to change it into other kinds of useful energy.

• True

• False

A closed switch means that the circuit is “on”.

• True

• False

An ammeter measures the current in a circuit.

• True

• False

You can control all devices in a series circuit with a single switch.

• True

• False

A complete circuit means that the circuit is “off”.

• True

• False
