1.	In ac circuit, resistance 5 ohm is connected with capacitor having capacitive reactance 12 ohm. Supply of 260 V is connected to the circuit. Calculate the current in the circuit.(a) 40 A(b) 10 A(c) 20 A(d) 30 AThis question was posed to me in a job interview.My question is from Resistance and Capacitance in Series in portion Single Phase Series Circuits of Basic Electrical Engineering
Answer» Right choice is (C) 20 A The EXPLANATION is: Z^2=R^2+XC^2 SUBSTITUTING the VALUES we get Z^2 = 5^2 + 12^2 Z^2 = 169 Z=13 Ω. I=V/Z = 260/13=20 A.
