Definition Electric Current Definition. An electric current is a flow of particles (electrons) flowing through wires and components. It is the rate of flow of charge. If the electric charge flows through a conductor, we say that there is an electric current in the conductor.
1.SI UNITS - AMPERE (A)
2.AMMETER
3.I =Q/t
Potential difference definition is - the difference in potential between two points that represents the work involved or the energy released in the transfer of a unit quantity of electricity from one point to the other.
1. SI UNIT -VOLTS
2. VOLTMETER
3. V=W/Q
Ohm' law
V=IR
ohm's law in Science. [ōmz] A law relating the voltage difference between two points, the electric current flowing between them, and the resistance of the path of the current. Mathematically, the law states that V = IR, where V is the voltage difference, I is the current in amperes, and R is the resistance in ohms.
