When electric bulbs are connected to battery they glow , state the energy transformation in two phenomena given below :
(1) In battery .
(2) In an electric bulb.

When two electric bulbs of 40W and 60W are connected in parallel, then the:

A battery lights a bulb. Describe the energy changes involved in the process.

An electric bulb is connected to a 220 V generator. The current is 0.50 A. What is the power of the bulb?

An electric bulb of 60 W is used for 6 h per day. Calculate the 'units' of energy consumed in one day by the bulb.

Two electric bulbs (60 W and 100 W respectively) are connected in series. The current passing through them is

Two electric bulbs are connected one by one across potential difference V At that time power consumed in them are P_1 and P_2 respectively. Now, if potential difference V is applied across series combination of these bulbs, what will be total power consumed ?

5 electric bulbs of 100 W are used for 8 hours, then …………… unit of energy would be consumed in 1 day. (4,5,8)
