Two identical bulbs of equal power are connected in parallel and they totally consume 110W at 220V . The resistances of each bulb is

In above question, if the bulbs are connected in parallel, total power consumed is

In above question, if the bulbs are connected in parallel, total power consumed is

If two identical heaters each rated as (1000 W, 220 V) are connected in parallel to 220 V, then the total power consumed is

Two identical electric lamps marked 500 W , 220 V are connected in series and then joined to a 110 V line. The power consumed by each lamp is

If two bulbs, both of rated power 100 W at 220 V, are connected in series with a 220 V supply, the total power consumed by the bulbs will be:

Four identical bulbs each rated 100 watt, 220 volts are connected across a battery as shown. The total electric power consumed by the bulbs is:

(a) Define Electric power. An electrial device of resistance R is connected across a source of voltage V and draws a current I. Derive an expression for power in terms of current and resistance. (b) Tow electric bulbs rated 100W , 220V and 60W, 220V are connected in parallel to an electric mains of 220V . Find the current draw by the bulbs form the mains.

A bulb of 40 W is connected across a source of 220 V . Find the resistance of the bulb.

If two identical heaters each rated as (1000 W, 220V) are connected are connected in parallel to 220 V, then the total power consumed is .

Two bulbs when connected in parallel to a source take 100 W each. The total power consumed when they are connected in series with the same source is
