To determine which bulb will give more illumination when a 25W-220V bulb is connected in series with a 100W-220V bulb to a 220V supply, we can follow these steps: ### Step 1: Calculate the Resistance of Each Bulb The resistance \( R \) of a bulb can be calculated using the formula: \[ R = \frac{V^2}{P} \] where \( V \) is the voltage rating and \( P \) is the power rating of the bulb. ...
