Using a cork in the circuit will break it, since it is an insulator. Removing one of the cells will reduce the flow of electricity and make the bulbs dimmer.

Replacing one of the cells with a wire:

Replacing one of the cells with a wire will make the bulbs dimmer in the simple circuit set up by Rizvi. Here's how it works:

Explanation:
- When two cells are connected in a circuit, they provide a certain amount of voltage to the bulbs, causing them to glow at their maximum brightness.
- By replacing one of the cells with a wire, the overall voltage provided to the bulbs decreases.
- This decrease in voltage results in the bulbs glowing dimmer than before.
- The resistance in the circuit increases due to the removal of one cell, causing the current flowing through the bulbs to decrease, leading to dimmer illumination.

Advantages of replacing a cell with a wire:
- It allows for an easy adjustment of the brightness of the bulbs in the circuit.
- It demonstrates the relationship between voltage, current, and resistance in a circuit.

Therefore, by replacing one of the cells with a wire in the simple circuit, Rizvi can make the bulbs dimmer.
