Answer :
Final answer:
When two bulbs are connected in parallel, the 100-watt bulb draws 0.45 Amps and the 60-watt bulb draws 0.27 Amps from the mains.
Explanation:
When two bulbs are connected in parallel, they have the same voltage across them. So, in this case, the voltage across both bulbs is 220 volts. Since the power of the first bulb is 100 watts and the power of the second bulb is 60 watts, we can use the formula P = IV, where P is power, I is current, and V is voltage, to find the current drawn by each bulb from the mains. Rearranging the formula, we get I = P / V. Plugging in the values, we get:
For the 100-watt bulb: I = 100 / 220 = 0.45 Amps
For the 60-watt bulb: I = 60 / 220 = 0.27 Amps
So, the 100-watt bulb draws 0.45 Amps and the 60-watt bulb draws 0.27 Amps from the mains.
