Solution
In series LCR circuit R = 18 Ω and impedance is 33 Ω An rms voltage 220V is applied across the circuit. The ture power consumed in AC circuit is 800W.
Explanation:
Given, R = 18Ω, Z = 33Ω, Vrms = 220 V
λ = 5 × 10-7 m
Power consumed in an AC circuit
P = ermsi.rms.cosΦ = erms.`"e"_"rms"/"Z"."R"/"Z"`
`[∵ cosphi = "R"/"Z"]`
= `(220xx220xx18)/(33xx33)`
= 20 × 20 × 2
= 800W
