Alternating Current

In the circuit of FIGURE 2 (in the attachment), the generator V1 has a voltage of 120 volts (r.m.s.) @ 60 Hz and generator V2 has a frequency of 50 Hz. The load is represented by an inductor of 0.1 H and a resistor of 20 Ohms.

(a) Determine the r.m.s. voltage of V2 if the reading on the ammeter, which reads true r.m.s., is to be 5 A.

(b) Calculate the power factor of the load for the conditions set in (a) above.
