How many electrons pass through a bulb in 1 min, if the current is 400 mA. (e=1.6xx10^(-19)C) ?
A bulb is rated as 55 W and 220 volt . It is connected across the supply of 220 V- 50 Hz. Calculate (a) rms current flowing through the bulb and (b) Peak current flowing through the bulb .
Fig. 12.10 A and B, show a bulb connected to a cell in two different ways. (i) What will be the direction of the current through the bulb in both the cases. (Q to P or P to Q) (ii) Will the bulb glow in both the cases? (iii)Does the brightness of the glowing bulb depend on the direction of current through it?
How many electrons per second flow through a filament of a 120 V and 60 W electric bulb ?
How many electrone flow per second through as electric bulb rated 220V,100W?
Two bulbs of 100 W and 40 W are connected in series. The current through the 100 W bulb is 1 A. the current through the 40 W bulb will be:
A 60 watt bulb operates on 220 V supply. The current flowing through the bulb is
