To solve the problem of finding the total power consumed by two bulbs rated at 100 W each when connected in series to a 220 V supply, we can follow these steps: ### Step 1: Determine the resistance of each bulb The power rating of each bulb is given as 100 W at a voltage of 220 V. We can use the formula for power to find the resistance of each bulb: \[ P = \frac{V^2}{R} \] ...
