Voltage

Definition

Voltage, also known as electric potential difference, is the measure of electrical potential energy per unit charge. It represents the force that drives electric current through a circuit.

Analogy

Think of voltage like a water pump. Just as a pump provides the pressure needed to move water through pipes, voltage provides the "push" or driving force for electric charges to flow in a circuit.

Related terms

Current: Current refers to the flow of electric charges (usually electrons) in an electrical circuit. It is directly proportional to voltage and inversely proportional to resistance.

Power: Power is the rate at which work is done or energy is transferred in an electrical circuit. It can be calculated by multiplying voltage and current (P = VI).

Electric Potential Energy: Electric potential energy refers to the stored energy that charged particles possess due to their position relative to other charged particles or objects with different potentials.
