Ampere Formula - Classical Physics

Ampere Formula:


Using Horsepower,

A = ( h * 746 ) / ( v * e ) ( For, Direct Current )
A = ( h * 746 ) / ( v * e * p ) ( For, Single Phase AC )
A = ( h * 746 ) / ( v * e * p * 2 ) ( For, Two Phase AC )
A = ( h * 746 ) / ( v * e * p * 1.73 ) ( For, Three Phase AC )


Using Kilowatts,

A = ( kw * 1000 ) / ( v ) ( For, Direct Current )
A = ( kw * 1000 ) / ( v * p ) ( For, Single Phase AC )
A = ( kw * 1000 ) / ( v * p * 2 ) ( For, Two Phase AC )
A = ( kw * 1000 ) / ( v * p * 1.73 ) ( For, Three Phase AC )


Using Kilovolts Ampere,

A = ( kva * 1000 ) / ( v ) ( For, Single Phase AC )
A = ( kva * 1000 ) / ( v * 2 ) ( For, Two Phase AC )
A = ( kva * 1000 ) / ( v * 1.73 ) ( For, Three Phase AC )


Where,

A = Ampere
kva = Kilovolt-Amp
v = Voltage
p = Power Factor
e = Efficiency
h = Horsepower
kw = Kilowatts
