You are given two nichrome wire of same length and different thickness Which wire will get heated first Give reason.? Asked Merlin Mary Mathew

Answer:

If the wires are connected one by one to a source, (or connected in parallel to the same source) the one having less resistance (Greater thickness) will get heated up first. This is because, for constant voltage, Heat dissipated is inversely proportional to resistance.

If both are connected in series to a power supply, the one with less thickness will get heated up as same current is flowing through both and then heat generated is directly proportional to resistance.
