Potential difference also known as voltage is the difference in the amount of energy that charge carriers have between two points in a circuit.
The larger the potential difference, the faster the current will flow and the higher the current.
Potential difference is measured in volts (V) and the instrument used in known as a voltmeter.
This concept provides the basis for understanding electric circuits.
Formula to calculate potential difference.
The formula used to calculate voltage is known as Ohm’s Law.
A current of 20 amperes travels through a circuit that has a 4 ohms resistor connected in parallel. Determine the potential difference of the circuit.
Therefore, the potential difference of the circuit is 80 V.
