The filament has high resistance compared to the connecting wire.

Vedclass · Answer

(B) The filament of the bulb and the connecting wires are connected in series,so the same current flows through both.According to Joule's law of heating,the heat produced is given by $H = I^2Rt$.Since the resistance $(R)$ of the connecting wires is negligibly small compared to the resistance of the filament,the heat produced in the wires is negligible.Conversely,the filament has a high resistance,which leads to a significant amount of heat production,causing it to glow.Therefore,the bulb glows while the connecting wires remain cool.

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