A wire of resistance 10 ohms is drawn out to three times its
original length. The new resistance will be
(1) 90 ohm
(2) 10 ohm
(3) 30 ohm
(4) 120 ohm
Answer Posted / p dilip kumar
As R= (SYMBOL ROW * L)/A
which means R is directly propotional to length
so when length of the wire is drawn three times obviously
the resistance will be multiple of 3.
Solution: 30 ohms
