Electricity and Circuits

Front

How is energy transferred from place to place?

Back

Energy can be transferred by electric currents, which can be used to produce motion, sound, heat, or light.

Front

How are electric currents produced?

Back

Electric currents may be produced by transforming the energy of motion into electrical energy, such as moving water driving a spinning turbine.

Front

What is a complete circuit?

Back

A complete circuit is a closed path through which electricity travels.

Front

What are the components of a circuit?

Back

Circuits are made up of a power source (like a battery), wires, and an object that converts energy into a different form (like a light bulb or buzzer).

Front

What happens when you connect a light bulb to a battery?

Back

Electrical energy moves from the battery to the bulb, creating a one-way flow of electricity.

Front

What produces electric current?

Back

The apparent motion of electrons along a conductor produces electric current.

Front

What is an electric current?

Back

An electric current is a flow of charge.
