You need to produce a set of cylindrical copper wires 2.5 m long that will have a resistance of `0.125Omega` each. What will be the mass of each of these wires? (Density of copper is `8.9xx10^3 kgm^(-3)` and resistivity of copper is `1.72 xx10^(-8) OmegaM).`

You need produce a set of cylindrical copper wire 3.50 m long will have a resistance of 0.125Omega each. What will be the mass of each of these wires? Specific resistance of copper =1.72xx10^-8Omega-m ,density of copper =8.9xx10^3kg//m^3

If the density of copper is 8.9xx10^(3)kg//m^(3) , find its relative density.

Calculate the mass of copper required to draw a wire 5 km long having resistance of 5 Omega .The density of copper is 8.9 xx 10^(3) kg m^(-3) and resistance of copper is 1.7xx 10^(-8) Omega m

Calculate the resistance of 1 km long copper wire of radius 1 mm . Resistivity of copper is 1.72 xx 10^-8 Omega m .

A uniform copper wire of mass 2.23 xx10^(-3) kg carries a current of 1 A when 1.7 V is applied across it. Calculate the length and the area of cross section, if the wire is uniformaly stretched to double its length, calculate the new resistance. Density of copper is 8.92xx10^3 kgm^(-3) and resistivity is 1.7xx10^(-8) Omega m.

A uniform copper wire of mass 2.23xx10^(-3) kg carries a current of 1 A when 1.7 V is applied across it. Calculate its length and area of cross-section. If the wire is uniformly stretched to double its length, calculate the new resistance. Density of copper is 8.92xx10^(3) kg m^(-3) and resistivity is 1.7xx10^(-8) Omega m.

When the resistance of copper wire is 0.1 Omega and the radius is 1mm, then the length of the wire is (specific resistance of copper is 3.14 xx 10^(-8) ohm xx m )

A copper wire 8 cm long is stretched to produce an extension of 0.8 cm in it. The lateral strain produced in the wire is , (if sigma of copper is 0.2)

The electric field in the copper wire of area of cross - section 2mm^(2) carrying a current of 1A is (use resistivily of copper is 1.7 xx 10^(-8) Omegam)
