graphite pencil

Heyyyyzz..
I've just been browsing other people's blogs,
and everyone's writing their's in formal language.
So I feel compelled to do the same from now on.
Okay, so the method is due tomorrow.
Here it is now, I've revised it a bit since my last post.

Aim: To find out if the power generated by a solar panel will vary with different colours of light.

Hypothesis: All colours of light generates the same amount of energy.

Equipments:
⚨ Solar Module 2.0 Volt 200mA (referred as "Solar Panel" in the method section)
⚨ 2 wires
⚨ Multimeter
⚨ Electric Lamp
⚨ 40W, 60W and 100W light bulbs
⚨ Colour Filters (red, orange, yellow, green, blue, violet)
⚨ Dark room


Method:
1. Connect one wire from the positive pole of the solar panel to the positive pole of the multimeter.

2. Connect one wire from the negative pole of the solar panel to the negative pole of the multimeter.

3. Set the multimeter to measure the voltage.

4. Place the red colour filter in front of a 40W light.

5. Place the solar panel at a distance of 120mm to the light bulb vertically above.

6. Observe the multimeter and record the reading shown.

7. Repeat steps 4 - 6 for the other 5 colours and also perform the same steps without any colour filter.

8. Set the multimeter to measure the current.

9. Repeat steps 4 - 7.

10. Repeat steps 4 - 9 with a 60W light bulb.

11. Repeat steps 4 - 9 with a 100W light bulb.
