Two identical electric bulbs X and Y are connected in two different circuits. Bulb X is connected to an AC power suply and bulb Y to a DC power supply . If potential difference across both the bulbs is same, which of the following bulb glow brighter ?

Explanation

To determine which bulb glows brighter between bulb X (connected to an AC power supply) and bulb Y (connected to a DC power supply) when both are subjected to the same potential difference, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Power Consumption**:
The brightness of a bulb is related to the power it consumes. The power \( P \) consumed by a bulb can be calculated using the formula:
\[
P = \frac{V^2}{R}
