The rms current in an rl circuit is 028 a when it is, Ask an Expert

Academics

The rms current in an RL circuit is 0.28 A when it is connected to an ac generator with a frequency of 60.0 Hz and an rms voltage of 25 V. (a) Given that the inductor has an inductance of 170 mH, what is the resistance of the resistor? ? (b) Find the rms voltage across the resistor. V (c) Find the rms voltage across the inductor. V (d) In this part you will use your results from parts (b) and (c) to show that Vrms, R2 + Vrms, L2 is equal to 25 V. First, calculate the squares of the individual rms voltages. (Vrms,R)2 = V (Vrms,L)2 = V Next, calculate the sum of the squares of the voltages. V2 Finally, calculate the square root of the sum of the squares. V
