Front

What is a circuit?

Back

A circuit is a closed loop that allows electricity to flow, consisting of a power source, wires, and devices like bulbs.

Front

What is the difference between potential energy and kinetic energy?

Back

Potential energy is stored energy based on an object's position, while kinetic energy is the energy of an object in motion.

Front

What is electrical energy?

Back

Electrical energy is the energy caused by the movement of electrons through a conductor.
