not a pencil

What colour of light will produce the maximum amount of electricity in a solar panel?

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 Panel
⚨ 4 wires
⚨ Multimeter
⚨ Resistor
⚨ Lamp with cardboard encircled around the light, leaving an opening
⚨ 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 resistor and another wire to the positive pole of the voltmeter.

2. Connect one wire from the negative pole of the solar panel to the negative pole of the resistor, and another wire to the negative pole of the voltmeter.

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

4. Place the solar panel underneath this now coloured light.

5. Observe the voltmeter and record the volts shown.

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

7. Repeat steps 3-6 with a 60W light,

8. Repeat steps 3-6 with a 100W light.

Of course, this is just an early stage of the assignment, so this report might need a little revising as I move along. But here's the general idea.

BYEEE!

Hellooooooooooooooooo~!

Turns out equipment can't be borrowed from school D:
I need to head over to Dick Smiths this weekend
to get a multimeter.

And also, instead of buying a light box, I'm just going to find a straight cylindrical cardboard tape around the lamp.

I also revised the equipment list. Check it out, woohoo:

~~⚨ Solar Panel~~
⚨ Multimeter
⚨ Resistor
~~⚨ Lamp with cardboard encircled around the light, leaving an opening~~
~~⚨ Colour filters (red, orange, yellow,~~ green, blue, violet)
~~⚨ Dark room~~

Byeeeez.

shaved pencil

Hellooooooooooooooooo!

Okay, today I bought some cellophane coloured paper.

Cellophane. Mister Cellophane. Shoulda been my name. Mister Cellophane

I bought just yellow, orange and red because I couldn't find any other colours in the store.

Something like this (found it on google):

I still need to get green, blue and violet...

Btw, just to recap, I'm doing this question:

4) What colour of light will produce the maximum amount of electricity in a solar panel?

I came up with this question because I reckon it relates to global issue, kinda? Like global warming is happening now...resources running out...people using solar panels more and more...yer know? :)

kthanxby.

charcoal pencil

Helloooooooooooooooooo!

Okay, this is stupid. Where am I going to find an ammeter, voltmeter, resistor and light box???

I can't just use my lamp, because the light spreads out. I need a light box with like un-dispersed light.

Wait, can we borrow from the school? Remind me to ask Ms Zhang later.

Anyways, I still need to buy colour filters/transparent paper. Today, my dad bought this electronic photo frame, and it came with a medium sized frame. I'm going to use the frame to stick my colour transparent paper on for the light to shine through.

Here's an updated list of equipments I still need to get, the striked words means that I already got them:

~~⚨ Solar Panel~~
⚨ Voltmeter
⚨ Ammeter
⚨ Resistor
⚨ Light Box
⚨ Colour filters (red, orange, yellow, green, blue, violet)
⚨ ~~Dark room~~
