(i) Total numbers of bulbs = 20
Numbers of defective bulbs = 4
Probability of getting a defective bulb = 4/20 = 1/5
(ii) One non defective bulb is drawn in (i) then...
Since each light can be switched on independently,
there are two options for each bulb (on or off)
∴Total no. of ways the bulbs can be operated= 210
This includes all the bulbs are...
The energy gap between the valence band and conduction band in an insulator is very large while in a conductor, the energy gap is very small or there is overlapping...
The resistance of the bulb is given by R=(V2/P). So, the resistance of 60 W bulb is more than the resistance of 100 W bulb. When they are connected in...
