In a RLC AC circuit R 775 Ohm L 0078 H C 000016 F Supply

In a R-L-C AC circuit, R = 7.75 Ohm, L = 0.078 H, C = 0.00016 F. Supply voltage is v = 310 sin(410t). Calculate the power loss in E. Your answer:__________

Solution

Answer:

Power loss in resistance = V²_rms /R = (V_m/2^1/2)² / R = V²_m /2R = (300 x 300) / (2 x 7.75) = 5806.45 Joule
