P=The power P in watts (W)
I=current I in amps (A)
V=the voltage V in volts (V)
So you can define watts are equivalent to amps times volts
Let take one Example
Example#1
Calculate the power utilization in watts(w) if the current is 5A and the voltage supply is 120V in a electrical circuit
Apply formula for the solution
P = 5A × 120V = 600W
P=The real power P in watts (W)
PF=the power factor PF
I=the phase current I in amps (A)
V=the RMS voltage V in volts (V)
So you can define watts(w) are equivalent to the power factor times amps(I) times volts(V)
Let’s take one example
Example#2
Find out the power utilization in watts(W) if the power factor(PF) is 0.8 and the phase current is 5A and the RMS(Root mean square) voltage supply is 120V?
Apply formula for the solution
P = 0.8 × 5A × 120V = 480W
P=The real power P in watts (W)
PF=the power factor PF times
I=the phase current I in amps (A)
VL-L=the line to line RMS voltage VL-L in volts (V)
So using above formula you can define watts(W) are equal to √3 power factor(PF) times amps times volts(V):
Example#3
Find out the power utilization in watts(W) If the power factor(PF) is 0.8 and the current is 5A and
the RMS(Root mean square) voltage supply is 120V?
Apply formula for the Solution
P = √3 × 0.8 × 5A × 120V = 831.36W
P=The real power P in watts (W)
PF=the power factor PF
I=the phase current I in amps (A)
VL-0=the line to neutral RMS(Root mean square) voltage VL-0 in volts (V)
So you can define watts(W) are equivalent to 3 times PF times amps(I) times volts(V)
Example#4
Find out the power utilization in watts(W) If the power factor(PF) is 0.8 and the current is 5A and
the RMS(Root mean square) voltage supply is 120V?
Apply formula for the Solution
watt(W) = 3 × .8 × 5A × 120V=1440W
