• The electric potential difference between the two points in an electric circuit carrying some current is the work done to move a unit charge from one point to other.
• volt is a derived SI unit of electromotive force or electric potential. ... Also, volt can be expressed as the potential difference that exists between two points in an electric circuit which imparts an energy of 1 joule (J) per coulomb of charge that flows through the circuit.
• Potential difference between two points in a current-carrying conductor is said to be 1 volt if 1 joule of work is done to carry a charge of 1 coulomb from one point to the other,i.e., 1volt=1joule1coulomb or 1V=1J1C=1JC-1.
• The S.I Unit of potential difference is volt (V). 1 volt =One volt is the potential difference between two points in a current carrying conductor when 1 joule of work is done to move a charge of 1 coulomb from one point to the other.
• voltmeter
• The S.I Unit of potential difference is volt (V). ... The potential difference is measured by an instrument called voltmeter.
• Measuring potential difference
• To measure the potential difference across a component, a voltmeter must be placed in parallel with that component in order to measure the difference in energy from one side of the component to the other. Potential difference is also known as voltage and is measured in volts (V).
