How to convert electric current in amps (A) to electric power in watts (W).
You can calculate watts from amps and volts. You can't convert amps to watts since watts and amps units do not measure the same quantity.
The power P in watts (W) is equal to the current I in amps (A), times the voltage V in volts (V):
P(W) = I(A) × V(V)
So watts are equal to amps times volts:
watt = amp × volt
or
W = A × V
What is power consumption in watts when the current is 5A and the voltage supply is 110V?
Answer: the power P is equal to current of 5 amps times the voltage of 110 volts.
P = 5A × 110V = 550W
What is power consumption in watts when the current is 5A and the voltage supply is 190V?
Answer: the power P is equal to current of 5 amps times the voltage of 190 volts.
P = 5A × 190V = 950W
What is power consumption in watts when the current is 5A and the voltage supply is 220V?
Answer: the power P is equal to current of 5 amps times the voltage of 220 volts.
P = 5A × 220V = 1100W
The real power P in watts (W) is equal to the power factor PF times the phase current I in amps (A), times the RMS voltage V in volts (V):
P(W) = PF × I(A) × V(V)
So watts are equal to power factor times amps times volts:
watt = PF × amp × volt
or
W = PF × A × V
What is power consumption in watts when the power factor is 0.8 and the phase current is 5A and the RMS voltage supply is 120V?
Answer: the power P is equal to power factor of 0.8 times current of 5 amps times voltage of 120 volts.
P = 0.8 × 5A × 120V = 480W
What is power consumption in watts when the power factor is 0.8 and the phase current is 5A and the RMS voltage supply is 190V?
Answer: the power P is equal to power factor of 0.8 times current of 5 amps times voltage of 190 volts.
P = 0.8 × 5A × 190V = 760W
What is power consumption in watts when the power factor is 0.8 and the phase current is 5A and the RMS voltage supply is 220V?
Answer: the power P is equal to power factor of 0.8 times current of 5 amps times voltage of 220 volts.
P = 0.8 × 5A × 220V = 880W
The real power P in watts (W) is equal to square root of 3 times the power factor PF times the phase current I in amps (A), times the line to line RMS voltage VL-L in volts (V):
P(W) = √3 × PF × I(A) × VL-L(V)
So watts are equal to square root of 3 times power factor PF times amps times volts:
watt = √3 × PF × amp × volt
or
W = √3 × PF × A × V
What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 120V?
Answer: the power P is equal to power factor of 0.8 times current of 3 amps times the voltage of 120 volts.
P = √3 × 0.8 × 3A × 120V = 498W
What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 190V?
Answer: the power P is equal to power factor of 0.8 times current of 3 amps times the voltage of 190 volts.
P = √3 × 0.8 × 3A × 190V = 789W
What is power consumption in watts when the power factor is 0.8 and the phase current is 3A and the RMS voltage supply is 220V?
Answer: the power P is equal to power factor of 0.8 times current of 3 amps times the voltage of 220 volts.
P = √3 × 0.8 × 3A × 220V = 1,205W
The calculation assumes the loads are balanced.
The real power P in watts (W) is equal to 3 times the power factor PF times the phase current I in amps (A), times the line to neutral RMS voltage VL-0 in volts (V):
P(W) = 3 × PF × I(A) × VL-0(V)
So watts are equal to 3 times power factor PF times amps times volts:
watt = 3 × PF × amp × volt
or
W = 3 × PF × A × V
How to convert watts to amps ►
The formula is 30 Amperes X 120 Volts = 3,600 Watts.
20-amp 120-volt circuit: 20 amps x 120-volts = 2,400 watts
Use this formula: p = v*i where p is your wattage, v is your voltage, and i is your amperage. Your 240 volts * 30 amps gives you 7200 watts, which is 7.2 kWh.
12 watts Higher power (2.4amp or 2.4A, 12Watt or 12W) chargers are often required by modern phones and tablets to charge the device.
