How many Amps in a Light Bulb?
To convert watt to watt for DC, single-phase AC, and three-Phase AC circuits, enter the power and voltage.
The power formula states that when P is power measured in watt, I is current in Amp, and E is voltage, then it's time to convert.
A slightly different formula is used to convert watt to watt for a single-phase AC circuit.
The power P in watt is divided by the power factor to arrive at the current I in Amp.The power factor calculator can help if you don't know what it is.
The formula to convert watt to watt is known for three-phase AC circuits.
The current I in Amp is equal to the power P in watt divided by the line to line power factor and the square root of 3.
The formula to convert watt to watt in three-phase AC circuits is:
The power P in watt is divided by the power factor to arrive at the current I in Amp.
If the resistance of the circuit is known using the formula, it is possible to convert watt to Amp.
The square root of the power P in watt is equal to the resistance R in ohms.
