Unformatted text preview: Vrms and 50 Hz? 120 V ~ 50 mH 100 mH 100 Ω 10 Ω +A B 2. The RMS voltage is 120 volts for the AC source V s in Figure 2. Figure 2 a) Find the resonant frequency (in Hertz) of the circuit in Figure 2. b) Calculate the current through the inductor and the total current drawn from the source at resonant frequency. c) Draw a phasor diagram of the voltage and currents in the circuit elements at resonant frequency. 3. A 50kVA transformer supplies a 20kW heating load at unity power factor. How much additional power of inductive load at 0.8 power factor can the transformer carry? V s +10 mH 10 Ω 1000 μ F...
