I dont know is your papers main idea stated clearly?
Answer:
the current consumed is 3.3 A
Explanation:
Given;
resistance, R = 30 ohms
inductance, L = 200 mH
Voltage supply, V = 230 V
frequency of the coil, f = 50 Hz
impedance, Z = 69.6 Ohms
The current consumed is calculated as;

Therefore, the current consumed is 3.3 A
Answer:
At 3 =99.60
At 6 =66.66
At 12 =33.38
Please see attachment for the percent consolidation.
Answer:
So 1/Rt=1/4+1/4+1/2=4/4 = 1 so Rtotal=1
