Q1.	The insulation resistance of a cable of length 10 km is 1 Mega Ohm's. For a length of 100 km of same cable, the insulation resistance will be
A.	1 Mega Ohm [Wrong Answer]
B.	10 Mega Ohm [Wrong Answer]
C.	0.1 Mega Ohm [Correct Answer]
D.	0.01 Mega Ohm [Wrong Answer]
View Answer 171 -152 Explanation:- Answer : C Discuss it below : Madan Raj Yadav Said on 2022-10-04 05:27:01 question asked about insulation resistance,not a wire resistance, so it is confussing, all length have same insulation Umapati k Said on 2018-08-15 02:52:00 Insulation resistance is inversely proportional to the length. As cable length will increase insulation resistance will decrease and vice versa... Click here for more comments

A.	R Ω [Wrong Answer]
B.	3/2 R Ω [Wrong Answer]
C.	3 R Ω [Wrong Answer]
D.	2/3 R Ω [Correct Answer]
