Here I am solving the question paper for the Joint Engineering Leleral Entry Test for you to enter the lateral entrance engineering course in the PDF file.
1. One kilogram of copper is drawn in wire of 1 mm diameter and wire of 2 mm diameter. Will be in resistance to two wires
Ratio
(A) 2: 1 (B) 1: 2 © 16: 1 (D) 4: 1
Answer: ©
2. An electric cable, which resists 0.2 a, saves 10 kW at 200 V dc in the factory. What is the efficiency of transmission?
(A) 65% (B) 75% © 85% (D) 95%
Answer: (D)
3. A wire of resistance 5 A is prepared so that its new length is 3 times its original length.What is the reconstruction of new wire?
(A) 45 Ω (B) 15 Ω © 5/3 Ω (D) 5 Ω
Answer: (A)
20. The ratio of Poisson content to 0.5 is 0.5. If a force is applied to the wire on this material, then the cross-partial area decreases
