SSC JE Electrical Important Questions with Answers 

The following SSC JE Electrical MCQs cover important technical concepts based on the core SSC JE electrical  syllabus. Check the correct answers and explanations to revise key topics. 

Question 1. The phenomenon of crawling in an induction motor is due to which of the following?

(A) Improper design of the machine

(B) Low voltage supply

(C) High load

(D) Harmonics developed in the motor

Answer: (D) Harmonics developed in the motor

Explanation: Crawling is a phenomenon in which an induction motor runs at approximately one-seventh of its synchronous speed. It occurs due to harmonics developed in the motor.

Question 2. What is the magnetising current of a transformer?

(A) The current flowing through the insulation between the primary and secondary windings

(B) The current drawn by the primary winding when the secondary is on open circuit

(C) The current drawn by the secondary winding when a load is connected

(D) The current flowing through the ferromagnetic core

Answer: (B) The current drawn by the primary winding when the secondary is on open circuit

Explanation: Magnetising current is also called excitation current. It flows through the primary winding when the transformer secondary is open and helps produce magnetic flux in the core.

Question 3. What is the advantage of using a DC welding machine over an AC welding machine?

(A) DC welding requires less power than AC welding

(B) DC welding does not require a transformer

(C) DC welding provides better control over arc stability

(D) DC welding eliminates the need for electrode coating

Answer: (C) DC welding provides better control over arc stability

Explanation: DC welding provides better arc stability, which helps produce smoother and more controlled welds.

Question 4. Which statements are correct for measuring current in a circuit using a CRO?

I. A low-resistance standard resistor is connected in series with the circuit.

II. The CRO is connected across the standard resistor to measure the voltage drop.

III. A high-resistance standard resistor is connected in parallel with the circuit.

IV. The CRO is connected in series with the circuit.

(A) Only IV

(B) Only I and IV

(C) Only III and IV

(D) Only I and II

Answer: (D) Only I and II

Explanation: A low-resistance standard resistor is connected in series with the circuit. The CRO measures the voltage drop across this resistor to determine the current.
