A bulb is connected to a cell and the potential differ-ence across the terminals of the bulb is 24 V. If 3 A of current flows through the bulb, then the resitance of its filament is `"_____"omega`.

An electric bulb is rated 60 W , 220 V . The resistance of its filament is

A bulb is marked 220 V and 40 W. Calculate the current flowing through the bulb and its resistance.

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 bulb whose resistance is 10 ohm is connected to a 6 V battery. Calculate the potential difference across the bulb.

If 90 W bulb is connected to a circuit with potential difference of 360 V,find the current flowing through the bulb?

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

A cell is connected to a bulb which develops a potential difference of 12 volt across it. The current in circuit is measured to be 2 ampere. Find the resistance offered by the filament of bulb to the flow of current.
