Question

What is the potential difference of a cell?

Answer 1

Hint:In order to answer this question we should first get some understanding about cells. A cell is a single electrical energy source that generates current through chemical reactions. An ‘electrical power supply' is an electrical cell. It turns chemical energy stored in the body into electrical potential energy.

Complete step-by-step solution:
The difference in electric potential between two points, which (in a static electric field) is defined as the work required per unit of charge to move a test charge between the two points, is known as voltage, electric potential difference, electromotive force (emf), electric pressure, or electric tension. Volt is the derived unit for voltage (potential difference) in the International System of Units. Work per unit charge is measured in joules per coulomb in SI units, with \[1\] volt equaling \[1\] joule (of work) for \[1\] coulomb (of charge).
Cell potential is the measurement of the potential difference between two half cells in an electrochemical cell. The capacity of electrons to pass from one half cell to the other causes the potential difference.
Electric potential differences between sites can be created by electric charge accumulation or imbalance (e.g. the well-known "static" and electronic capacitor), electric current through a magnetic field, time-varying magnetic fields (e.g. dynamo or generator), or a combination of these three.

Note:The sites over which the voltage is measured must be specified explicitly or implicitly when specifying a voltage measurement. When using a voltmeter to detect potential difference, connect one of the voltmeter's electrical leads to the first location and the other to the second.
