An wire of resistance R is elongated n-fold to make a new uniform wire. The resistance of new wire

A metal wire of resistance 3Omega is elongated to make a uniform wire of double its previous length. This new wire is now bent and the ends joined to make a circle. If two points on this circle make an angle 60^(@) at the center, the equivalent resistance between these two points will be :

A metal wire of resistance 3 omega is elongated to make a unform wire of double its previous length. This new wire is now bent and the ends joined to make a circle. If two points on this circle make an angle 60^(@) at the centre, the equivalent resistance between these two points will be :

If a wire of resistance R is melted and recasted in to half of its length, then the new resistance of the wire will be

If a wire of resistance R is melted and recasted in to half of its length, then the new resistance of the wire will be

If a wire of resistance R is melted and recasted to half of its length, then the new resistance of the wire will be

A wire of resistance R is stretched to three times its original length. The new resistance is

If a uniform wire of resistance R is uniformly strethced to n times the orginal length , then new resistance of the wire becomes

If a uniform wire of resistance R is uniformly strethced to n times the orginal length , then new resistance of the wire becomes

If a uniform wire of resistance R is uniformly strethced to n times the orginal length , then new resistance of the wire becomes
