A piece of silver has a resistace of `2 Omega`. What will be the resistance of constantan wire of two-third length and one-third diameter, if the specific resistance of constantan is 30 times that of silver.

A piece of silver ahs a resistance of 1 Omega . What will be the resistance of a constantan wire of one-third length and one-half diameter, if the specific resistance of constantan is 30 times that of silver ?

A wire of silver has a resistance of 1 ohm. Specific resistance of constantan is 30 times the specific resistance of silver. Find the resistance of a constantan wire whose length is one third length of the silver wire and radius half the radius of the silver wire.

The resistance of eureka wire is 2.5 Omega . What is the value of specific resistance of write of 14 m length and diameter of 0.14 cm ?

A resistance wire made from German silver has a resistance of 4.25 Omega . Calculate the resistance of another wire, made from the same material, such that its length increases by 4 times and area of cross-section decrease by 3 times.

What will be the change in resistance of a constantan wire when its radius is made half and length reduced to one-fourth of its original length ?

What will be the change in resistance of a constantan wire when its radius is made half and length reduced to one-fourth of its original length ?
