Alternating CurrentMedium
Question
In an A.C. circuit, the current flowing in inductance is I= 5 sin (100t - π / 2)amperes and the potential different is V = 200 sin(100t) volts. the power consumption is to
Options
A.100watt
B.40watt
C.20watt
D.Zero
Solution
Power, P = Ir.m.s. × Vr.m.s. × cos φ
In the given problem, the phase difference between voltage and current is p/12. Hence
P = Ir.m.s. × Vr.m.s. × cos(π/2) = 0
In the given problem, the phase difference between voltage and current is p/12. Hence
P = Ir.m.s. × Vr.m.s. × cos(π/2) = 0
