Rohit bought `2 1/4` metre of iron wire and `3 1/3` m of copper wire. (i) How much wire did he buy altogether? (ii) How much more copper wire is more than iron wire

how copper wire reacts with oxygen to produce:

A copper wire of length 1m is stretched by 1cm. Find the strain on the wire

Two wires are made having same length l and area of cross-section A. Wire 1 is made of copper and wire 2 is made of aluminium. It is given that the electrical conductivity of copper is more than that of aluminium. In this context, which one of the following statements is correct?

The frequency ratio of two wires of copper is 2 : 3 if the diameter of the first wire is 0.6mm, the diameter of the other wire is -

IF the length of a copper wire is increased by 0.1%, show that the resistance of the copper wire will increase by 0.2%.

A copper wire 36m long with diameter 2 mm is melted to form a sphere. Find volume of the copper wire.

A copper wire of length 1 m and radius is joined in series with an iron wire of length 2 m and radius 3 mm and a current is passed through the wire. The ratio of the current density in the copper and iron wires is

Form 10 1/2 metres long wire Samir cut off 5 pieces of 1 1/4 metre each. How much length of the wire was left?
