Question

define ,potential difference, free electrons ,electric current, one ampere.​

Answer 1

Potential difference is the difference in the amount of energy that charge carriers have between two points in a circuit.The potential difference (which is the same as voltage) is equal to the amount of current multiplied by the resistance. A potential difference of one Volt is equal to one Joule of energy being used by one Coulomb of charge when it flows between two points in a circuit.

Answer 2

Answer :-

Potential Difference :-

Potential difference is the difference in the amount of energy charge carries have between two points in a circuit Potential difference (p.d) is measured in volts is called voltage .

Free electrons : -

An electron moving in vacuum is called free electrons .

Electric current :-

An electric current is a stream of charged particles, such as electrons or ions, moving through an electrical conductor or space . It is measured as the net rate of flow of electric charge through a surface or into a control volume .

One ampere :-

An ampere is a unit of measure of the rate of electron flow or current in a electrical conductor .
