Design an experiment to investigate how the length of a wire affects the brightness of a light bulb in a simple circuit.Your response must include:Material with quantityStepwise methodologySafety precautionsB

Materials:

1. A power source (battery)
2. A light bulb
3. Wires of different lengths (for example, 1m, 2m, 3m, 4m, 5m)
4. Wire cutter
5. Tape
6. A light meter (to measure brightness)

Stepwise Methodology:

1. Set up a simple circuit with the battery, a piece of wire (start with the 1m wire), and the light bulb. Make sure all connections are secure.
2. Turn on the circuit and measure the brightness of the light bulb using the light meter. Record the result.
3. Repeat steps 1 and 2 with the other pieces of wire, one at a time. Make sure to record the brightness of the light bulb for each length of wire.
4. Compare the results. If the brightness of the light bulb changes with different lengths of wire, this could indicate that the length of the wire affects the brightness of the light bulb.

Safety Precautions:

1. Always handle the wire cutter with care to avoid injury.
2. Do not touch the bare wires when the circuit is on to avoid electric shock.
3. Make sure the power source is not too strong for the light bulb to handle, as this could cause the bulb to explode.
4. Always work in a well-ventilated area to avoid inhaling any potential fumes from the battery or wires.
5. If the wire or bulb becomes too hot, turn off the circuit immediately and allow it to cool before handling.
