Two bulbs, one rated 100 W at 220 V and other 200 W at 220 V are connected In series
In parallel to the electric main supply of 220 V.
Find the current drawn in each case.

Explanation

To solve the problem of finding the current drawn by two bulbs rated at 100 W and 200 W when connected in series and in parallel to a 220 V supply, we will follow these steps:

### Step 1: Calculate the Resistance of Each Bulb
We know the power (P) and voltage (V) ratings of the bulbs. We can use the formula:
\[ R = \frac{V^2}{P} \]
where \( R \) is the resistance, \( V \) is the voltage, and \( P \) is the power.
