The voltage across the circuit, often denoted by \( V \) or \( E \), is the electrical potential difference between two points in the circuit. It represents the energy per unit charge provided by an energy source, such as a battery or a generator, to move electric charges (electrons) through the circuit.
Mathematically, voltage (\( V \)) is defined as the work done per unit charge:
\[ V = \frac{W}{Q} \]
where: – \( V \) is the voltage, – \( W \) is the work done on the charge, – \( Q \) is the electric charge.
In a closed circuit, the voltage is responsible for driving the electric current through the circuit, which is the flow of electric charge. Voltage provides the “push” that moves electrons in a specific direction within the circuit.
