Answer 1

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, V_rms = 220 V 

λ = 5 × 10^-7 m

Power consumed in an AC circuit

P = e_rmsi._rms.cosΦ = e_rms.`"e"_"rms"/"Z"."R"/"Z"` 

`[∵ cosphi = "R"/"Z"]`

= `(220xx220xx18)/(33xx33)`

= 20 × 20 × 2

= 800W
