Answer:
Since, 10 bulbs are connected in so we can find the resistance of one bulb by using the formulae of power P = voltage V^2 / resistance R. Thus, R will be 220*220/60 which is approximately 806 ohm.
Since, the bulbs are in series thus equivalent resistance will be 120*806=8060ohm.
So, now we can get the value of current in each bulb by V=IR or I =220/8060=0.027 ampere.
Thus, the power consumed will be P = I^2*R = 0.027*0.027*806 = 0.58 watt will be the power consumed.
