A device that helps to maintain a potential difference across a conductor

A device that helps to maintain a potential difference across a conductor Correct Answer Both 1 and 2

Concept:

  • Potential Difference: It can be defined as the difference in the amount of energy that the charge carrier has between the two pints in the circuit is called a Potential Difference.
    • It is always measured in the volt and is also known as voltage.
    • It may also be defined as the amount of work done in moving a specific charge from one point to another point.

Additional Information

  • An electrochemical cell is a device that can generate electrical energy from the chemical reactions occurring in it, or use the electrical energy supplied to it to facilitate chemical reactions in it.
  • These devices are capable of converting chemical energy into electrical energy, or vice versa.
  • A common example of an electrochemical cell is a standard 1.5-volt cell which is used to power many electrical appliances such as TV remotes and clocks.

Important Points

  • In the circuit, the electrons only flow when there is a potential difference between the two points.
