Two wire A & B are of the same metal and are of same length have area of cross section in the ratio of 2:1 If the same potential difference is applied across each wire. What will be the ratio of the current flowing through the wires A & B ?

Two wires of the same metal have the same length, but their cross-sections are in the ratio of 3:1. They are joined in series. The resistance of the thicker wire is 10 Omega . The total resistance of the combinations will be

State the formula correlating the electric current flowing in a conductor and in voltage applied across it also, show this relationship by drawing a graph. What would be the resistance of a conductor if the current flowing throught it is 0.35 ampere when the potential difference across it is 1.4 volt.

Compare the resistance of two wires of same material. Their lengths are in the ratio 2:3 and their diameters are in the ratio 1:2

A wire connected to a bulb does not glow, whereas the filament of the bulb glows when the same current flows through them.Why?

Two metallic wires of the same material B, have the same length out cross-sectional area is in the ratio 1:2. They are connected (i) in series and (ii) in parallel. Compare the drift velocities of electrons in the two wires in both the cases (i) and (ii) .
