a measure of the amount of difference in electrical charge between two points, called the potential difference (i.e., measure of electrical potential energy; if separated charges of opposite charge are allowed to come together, energy, the ability to do work is released)
Define voltage.
The measure of the amount of difference in electrical charge between two points is called the potential difference. It is also referred to as voltage or electric potential. Potential difference is a fundamental concept in the study of electricity, and is measured in volts (V).
Potential difference is a measure of the electrical potential energy between two points in an electric circuit. If two charges of opposite polarity are separated by a distance, they have a potential energy associated with them. The potential difference is a measure of the amount of energy that is released when the two charges are allowed to come together and balance out.
The voltage is measured across a device or component in an electric circuit using a voltmeter. A voltmeter is typically connected in parallel to the component, allowing it to measure the potential difference between the points that the component connects.
In summary, the potential difference is a measure of the amount of electrical energy available between two points in an electric circuit. It is a fundamental concept in the study of electricity and is measured in volts. The potential difference can be measured using a voltmeter connected in parallel to the component in the circuit.
