Expert Solution
Introduction

We know that power = V. I = V2R

Where V =voltage and I= current and resistance of bulb

The resistance is same for all bulbs as all are identical.

i.e Power α V2

Now we know that in bulb are connected in parallel and in such a connection the voltage received by each bulb will be same as the battery voltage.

Power will be same for all the three bulbs.
