Electromagnetism and Circuits Review

Front

What happens to the brightness of the other bulb if one bulb goes out in a parallel circuit?

Back

The other bulb's brightness stays the same.

Front

What is it called when an electrical charge builds up on an object?

Back

Static electricity.

Front

How can the strength of an electromagnet be increased?

Back

By increasing the coils of wire around the iron.

Front

Why does the light from a flashlight become dimmer as the batteries start to run out?

Back

The energy stored in the batteries decreases.

Front

What produces a magnetic field?

Back

Electric current.

Front

What is the difference between current electricity and static electricity?

Back

Current electricity is the flow of electric charge, while static electricity is the buildup of electric charge on an object.

Front

What is a series circuit?

Back

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

Front

What is a parallel circuit?

Back

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

Front

What is an electromagnet?

Back

A type of magnet in which the magnetic field is produced by an electric current.

Front

How does increasing the voltage affect the current in a circuit?

Back

Increasing the voltage generally increases the current, assuming resistance remains constant.
