The power values of the loads in the circuit given in the figure are given below. Accordingly, which of the following is the RMS value of the Vs voltage amplitude?
Load 1 (L1): the power factor is 1 and draws 13 kW of power,Load 2 (L2): draws 1 kVA at a forward power factor of 0.6,Load 3 (L3): draws 4 kW of average power and gives 3 kVAR of reactive power.
The values of the elements in the circuit given in the figure are given below. Find the average power value on the R2 resistor.
(Hint: First find the current of the R2 resistor with the loop current method. Four mutual inductance effect expressions should be added to each of the two loop equations.)
Vs=238 voltsR1=13 ohmsR2=15 ohms
