CBSE Class 7 Answered
Why is it that same current flowing through the tungsten filament of an electric bulb produces enormous heat but almost negligible heat is produced in the connecting wires of the bulb?

Expert Answer
This is because of the fact that the fine tungsten filament has a very high resistance whereas copper connecting wires have very low resistance.
