Energy and Circuits

Front

What is mechanical energy?

Back

Mechanical energy is the energy that an object has due to its motion or position. It can be kinetic energy (energy of motion) or potential energy (stored energy due to position).

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor. It is used to power devices like light bulbs and motors.

Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow from a power source to a device and back again.

Front

What is a series circuit?

Back

A series circuit is a type of electrical circuit where the components are connected in a single path, so the same current flows through all components.

Front

What happens if one bulb in a series circuit burns out?

Back

If one bulb in a series circuit burns out, the circuit is broken, and all bulbs will go out.

Front

What is a parallel circuit?

Back

A parallel circuit is a type of electrical circuit where the components are connected across common points, allowing multiple paths for current to flow.

Front

What happens if one bulb in a parallel circuit burns out?

Back

If one bulb in a parallel circuit burns out, the other bulbs will remain lit because the circuit is still complete through the other paths.

Front

What is a switch?

Back

A switch is a device that can open or close a circuit, allowing or stopping the flow of electricity.

Front

What is a battery?

Back

A battery is a device that stores chemical energy and converts it into electrical energy to power circuits.

Front

What is resistance in a circuit?

Back

Resistance is a measure of how much a material opposes the flow of electric current. It is measured in ohms.
