DefinitionCurrent is the rate at which electric charge flows past a point in a circuit. In other words, current is the rate of flow of electric charge.Voltage, also called electromotive force, is the potential difference in charge between two points in an electrical field. In other words, voltage is the "energy per unit charge”.
SymbolIV
UnitA or amps or amperageV or volts or voltage
SI Unit1 ampere =1 coulomb/second.1 volt = 1 joule/coulomb. (V=W/C)
Measuring InstrumentAmmeterVoltmeter
RelationshipCurrent is the effect (voltage being the cause). Current cannot flow without Voltage.Voltage is the cause and current is its effect. Voltage can exist without current.
Field createdA magnetic fieldAn electrostatic field
In series connectionCurrent is the same through all components connected in series.Voltage gets distributed over components connected in series.
In a parallel connectionCurrent gets distributed over components connected in parallel.Voltages are the same across all components connected in parallel.
