• # question_answer 43) An rms voltage of 110 V is applied across a series circuit having a resistance 11 Q and impedance 22Q. The power consumed is- A) 275 WB) 366 WC) 55 0 W             D) 1100 W

$P={{E}_{v}}{{I}_{v}}\,\,\cos \phi$ $P={{E}_{v}}\,\,\frac{{{E}_{v}}}{Z}\frac{R}{Z}$ $or\,\,P=\frac{{{E}_{v}}^{2}R}{{{Z}^{2}}}\,\,=\,\frac{110\times 110\times 11}{22\times 22}\,\,W=275\,\,W$
