Question

A uniform wire of resistance 50 ohms is cut into 5 equal parts. These parts are now connected in parallel.Then the equivalent resistance of the combination is
a) 2 ohm
b) 12 ohm
c) 250 ohm
d) 6250 ohm​

Answer 1

Answer:

As resistance is directly proportional to the length of wire, when you cut the wire in 5 equal parts, the resistance gets reduced by 5 times i.e 10 ohms. As 5 resistors each with 10 ohms are connected in parallel,the equivalent resistance will be 10/5 = 2 ohms…
