Solution :-
- Resistance = R = 4 Ω
- Impedance = Z = 5 Ω
- V rms = 200 V
- I rms = 1.5 A
We need to find the average power consumed over a full cycle ,
As per the formula ,
we know that ,
Now let's substitute the given values in the above equation ,
Hence ,
The average power consumed over a full cycle is 240 W

P average =Vrms.Irms.cosθ
=Vrms.Irms.R/z
= 200 × 1.5 × 4/5
P average = 240 W
hence option C is correct answer ✅
