Voltage potential is a measure of the electric potential energy per unit charge at a particular point in an electric field. It is often referred to as voltage or electric potential difference and is measured in volts (V).
Voltage potential can be calculated by dividing the work done in moving a charge from one point to another by the amount of charge. This can be represented by the equation V = W/Q, where V is the voltage potential, W is the work done, and Q is the amount of charge.
Potential difference is the difference in voltage potential between two points in an electric field. It is the measure of the change in electric potential energy per unit charge between those two points and is also measured in volts (V).
To find the potential difference in a circuit, you can use the equation V = IR, where V is the potential difference, I is the current, and R is the resistance. You can also use a voltmeter to directly measure the potential difference between two points in the circuit.
The unit of measurement for both voltage potential and potential difference is volts (V). This unit is named after the Italian physicist Alessandro Volta, who first discovered the concept of electric potential in the late 18th century.
