Answer :
Final answer:
When two bulbs are connected in parallel to an electric mains of 220 V, the 100 W bulb draws approximately 0.4545 A and the 60 W bulb draws approximately 0.2727 A.
Explanation:
When two bulbs are connected in parallel, the voltage across each bulb is the same as the voltage of the electric mains, which is 220 V in this case. Since the voltage is the same, the current drawn by each bulb can be calculated using Ohm's Law, which states that current (I) is equal to voltage (V) divided by resistance (R).
The power rating of a bulb is given by the equation P = IV, where P is power, I is current, and V is voltage. So, we can find the current drawn by each bulb by rearranging the equation to I = P/V.
For the 100 W bulb: I = 100 W / 220 V = 0.4545 A
For the 60 W bulb: I = 60 W / 220 V = 0.2727 A
Therefore, the current drawn by the 100 W bulb is approximately 0.4545 A and the current drawn by the 60 W bulb is approximately 0.2727 A.
