Electric Current - is the rate of flow of electrons in a conductor. The SI Unit of electric currentis the Ampere.
Voltage Definition and Formula
- As per voltage definition, it is the difference in the electric potential between two points. It is the work done in moving a charge from one pole to another through a wire.
- To determine the voltage between any two points, both a static electric field and a dynamic electromagnetic field is considered.
- The mathematical representation of voltage is as follows:
- V = IR
- V = Voltage in volts
- I = Current in amperes
- R = Resistance in ohms
