Detailed Solution for Technical Test SSC JE: Electrical Engineering (EE)- 3 - Question 10

At resonant frequency, an R-L-C series circuit draws maximum current because:

  1. the difference between capacitive reactance and inductive reactance is zero

Explanation:

In a series R-L-C circuit, resonance occurs when the inductive reactance (XL​) and capacitive reactance (XC​) are equal in magnitude but opposite in phase. At this point, they cancel each other out, resulting in the total reactance of the circuit being zero. This means that the only impedance in the circuit is the resistance (R), which is at its minimum. Hence, the circuit draws maximum current because the impedance is minimized to just the resistance.

The correct answer is:

  1. the difference between capacitive reactance and inductive reactance is zero

Detailed Solution for Technical Test SSC JE: Electrical Engineering (EE)- 3 - Question 30

Correct Answer :- B

Explanation : The effect of armature reaction mmf is purely demagnetizing in zero pf lagging load condition. This can be explained in 2 methods :

In Zero power factor lagging load, the load current is lagging behind the excitation voltage by 90 degree.

Due to zero power factor lagging load, the current in phase “a” of armature winding will become maximum when the field poles have advanced by 90 degree in assumed counter-clockwise direction.
