In an ac circuit, the applied voltage and flowing current are E = Eosi

1.	In an ac circuit, the applied voltage and flowing current are E = Eosin ωt and I = Iosin (ωt + π/2) respectively. What is the average power consumed 2 in one cycle in this circuit?
Answer» Given E = = E_osin ωt I= I_osin (ωt + π/2) Since difference between voltage and current is π/2 Hence, Power of cos ϕ = cos π/2 = 0 Power consumption = E_RMSI_RMS cos ϕ= 0

Answer»

Given E = = E_osin ωt

I= I_osin (ωt + π/2)

Since difference between voltage and current is π/2

Hence,

Power of cos ϕ = cos π/2 = 0

Power consumption = E_RMSI_RMS cos ϕ= 0
