Answer :
Final answer:
When two lamps are connected in parallel to the electric main supply, the current drawn by each lamp can be calculated using Ohm's Law.
Explanation:
When two lamps are connected in parallel, the voltage across each lamp remains the same.
The resistance of a lamp can be calculated using Ohm's Law, which states that resistance is equal to voltage divided by current (R = V/I).
Since the voltage across both lamps is 220 V and the supply voltage is 2 V, the current drawn by each lamp can be calculated as follows:
For the 100 W lamp:
Power (P) = V * I --> 100 = 220 * I --> I = 100/220 = 0.45 A
For the 60 W lamp:
Power (P) = V * I --> 60 = 220 * I --> I = 60/220 = 0.27 A
Therefore, the current drawn by the 100 W lamp is 0.45 A and the current drawn by the 60 W lamp is 0.27 A.
