Electricity Test Review

Front

What are the two poles of a compass?

Back

North & South

Front

What can be assumed about the charge on a soda can if it is attracted to a negatively charged balloon?

Back

It is positively charged.

Front

Why did Isabella's compass fail to give an accurate reading under a power line?

Back

A compass works with a magnetic field, and the electric current running through the lines above it would interfere with the magnetic field.

Front

What happens to the force between two magnets as the distance between them increases?

Back

The force decreases.

Front

What is a circuit in which the current is divided into two or more paths called?

Back

Parallel circuit.

Front

What is static electricity?

Back

Static electricity is the buildup of electric charge on the surface of objects.

Front

What is the difference between a series circuit and a parallel circuit?

Back

In a series circuit, the current flows in a single path, while in a parallel circuit, the current can flow through multiple paths.

Front

What is voltage?

Back

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

Front

What is the role of a resistor in an electric circuit?

Back

A resistor limits the flow of electric current.

Front

What is an electric current?

Back

An electric current is the flow of electric charge, typically measured in amperes.
