A wire of 1 Ω has a length of 1 m. It is stretched till its length increases by 25%. The percentage change in the resistance to the nearest integer is -
A wire 1 m long has a resistances of 1Ω. It is uniformly stretched, so that its length increases by 25%.Therefore its resistance will increase by:
A wire 1 m long has resistance of 1ohm. If it is uniformly stretched so that it's length increases by 25percentage then it's resistances will increase by what
