Circuits and Electricity

Front

What is an open circuit?

Back

An open circuit is a circuit that is not complete, meaning that there is a break in the path for current to flow.

Front

What is a direct current?

Back

Direct current (DC) is a type of electrical current that flows in one direction only.

Front

What happens to total resistance when resistors are added in series?

Back

The total resistance increases as more resistors are added in series.

Front

How can you complete an incomplete circuit?

Back

To complete an incomplete circuit, a wire should connect the two points that are not connected.

Front

What happens when a switch in a circuit is opened?

Back

When a switch is opened, the circuit is broken, and the light bulbs will not work.

Front

What is a closed circuit?

Back

A closed circuit is a complete circuit that allows current to flow.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of circuit where there are multiple paths for current to flow.

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 resistance in a circuit?

Back

Resistance is a measure of the opposition to the flow of electric current, measured in ohms.

Front

What is the role of a battery in a circuit?

Back

A battery provides the electrical energy needed to push current through the circuit.
