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 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.

The specific resistance of silver is _______

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 ?

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 ?

The resistance of a conductivity wire of length 1.1 m and of diameter 0.14 mm is 30 Omega . Calculate its resistivity.
