To solve the problem of how the brightness of the bulb changes when a dielectric slab is introduced between the plates of a capacitor connected in series with an AC source, we can follow these steps: ### Step 1: Understand the Circuit Configuration We have a bulb (B) and a capacitor (C) connected in series to an AC source. The brightness of the bulb depends on the current flowing through the circuit. **Hint:** Remember that the brightness of a bulb is directly proportional to the current flowing through it. ### Step 2: Analyze the Effect of the Dielectric ...
