Hi guys, as the title above describes, I am interested in majoring in Aerospace Engineering. However, I plan to take Mechanical first because I feel that it's a great foundational degree to start off with. Just wondering whether it is possible to move on to Aerospace Engineering for graduate...

should i connect the voltmeter in parallel to the LED/variable resistor or the solar cell? i'm sure it's the solar cell if I'm not wrong

It seems that I've got to get a a variable resistor for this experiment then. At the current moment I'm experiencing falling efficiency. Sorry about missing your last post. I cannot get a variable resistor till after the holidays, so i'll have to wait until then...

thanks a lot for the pointers. i'm only considering US, Canada and Japan. Seems like I've got to email them...

So does this mean the top schools in Canada such as mcgill and toronto accept math SL? How about America? know anything about their system and whether they'll accept math SL. Heard everything was based on calculus.

At the current moment, I am taking HL Math and Physics. However, is it important to take HL Math in order to apply for engineering courses or physics courses? Can I just take SL Math and HL Physics?

first of all I'm at high school level second of all, I'm asking in a situation where the temperature does not increase. so let's say the temperature does not increase, will there be a change in efficiency? for my high school essay, I'm conducting 2 experiments. 1 on temperature against...

Actually I have one more question to ask, in theory does the efficiency of the solar cell increase with light intensity? Or the maximum power point changes only?

Thanks you so much guys, I understand what's wrong with my experiment now. It seems that I cannot get my resistor till after the holidays so in the mean time I've got to work on the theory of my extended essay first...

It looks like I'm taking the first possibility for my experiment at the moment. I'm not sure what you mean by load, I checked wiki and it says it has something to do with power output? I was supposed to carry out two experiments, one was this light intensity one and the other was altering...

i'm sorry i don't know how to post a picture of my setup. But i can help to describe the setup. Ok there is a light source that shines on the solar cell. The solar cell is then connect in parallel to the voltmeter (multimeter), and series to the ammeter (another multimeter). That's it

Oh no, I didn't use a load because I didn't think it was needed. The current and voltage definitely varies depending on the light intensity. Because as the distance increases between the solar cell and the light source, the current and voltage decreases.

so you mean that the maximum power it can reach will change with light intensity, efficiency will not change?

Oh I'm making practical measurements. The solar cell is connected to a voltmeter and an ammeter to record the current and voltage and to find out power output. To measure power input, I used a 100W bulb and shone the light at the solar cell from different distances. I recorded the lux readings...

It seems as there is more lux then the solar cell would be less efficient
