(a) How does the wire in the filament of a light bulb behave differently to the other wires in the circuit when the current flows?
(b) What property of the filament wire accounts for this difference?

The filament of an electric bulb is made of a thin wire of :

What is the difference between heater wire and fuse wire ?

Apart from the live wire, what are the two other wire's in the household circuit?

When the fuse wire melts , the circuit is broken. What happens to the current in the circuit ?

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

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

The filament of a bulb glows when current flows through it but the wires connected to it do not. Explain.

The filament of a bulb takes a current 100 mA when potential difference across it is 0-2 V. When the potential difference across it becomes 1.0 V, the current becomes 400 mA. Calculate the resistance of the filament in each case and account for the difference.

Two wires made of same material but of different diameters are connected in series in a circuit. The current flows in the combination of wires. When the current flows from the wire with larger diameter to the one with smaller diameter, what happens to the drift velocity of electrons ?
