Two wires A and B of the same material and having same length, have their cross-sectional areas in the ratio `1:4`. what should be the ratio of heat produced in these wires when same voltage is applied across each ?

Two wires A and B of same length and same material, have their cross sectional areas in the ratio 1:4. What would be the ratio of heat produced in these wires when the voltage across each is constant?

Two wires A and B of the same metal have the same across sectional area and have their lengths in the ratio 2:1 What will be the ratio of currents flowing through them respectively, when the same potential difference is applied across each of them?

Two wires of the same material of same length have area of cross sections in the ratio 1:2 If forces are applied in the ratio 2:1 to extend them what be the ratio of their extension in length ?

Two wires A and B are of same metal, have the same area of cross-section and have their lengths in the ratio 2 : 1 . What will be the ratio of currents flowing through them respectively when the same potential difference is applied across the length of each of them ?

Two wires A and B are of same metal, have the same area of cross-section and have their lengths in the ratio 2 : 1. What will be the ratio of currents flowing through them respectively when the same potential difference is applied across the length of each of them ?

. Two wires of the same radius and material have their lengths in the ratio 1 : 2. If these are stretched by the same force the strain produced in the two wires will be in the ratio
