What'd you guys get for the mass of the scooter, the diameter for last question, the height of the scooter?
Mass of scooter: 7 Kg
Diameter: 9.6 so therefore minimum is =10
Height: 0.45 m

mass is 7k or something, height 0.45m, and 10 for diameter
yep that should be right checked with my mates from school

what was the function of capacitor, variable capacitor, earth and other ones signal diode?

One question, did you guys need to section the cylinder thing in the middle for the last question. I wasn't sure

#### StudyOnly

##### Active Member
didn't know those and also the impedance one

I don't think so, I didn't

yep those capacitors were weird and for the diode i just said a one-way component that acts as a voltage regulator allows the current to flow in one direction, so just the general definition, the rest bullshitted

i didnt either cause its the actual pin piece so u dont section it

#### Liam Hu1

the varied capacitor change the channel, capacitor is used to demodulate. I guess...

[/QUOTEdamn, I did

I think its fair to say, that this one has been harder than the last five years (imo)

variable capacitor allows to tune for certain frequency, the standard capacitor is used to provide a more constant level of charge in the circuit - makes the output curve smooth. The diode is for rectification from AC to DC

what did youse get for the 1st q Multis

This subject is actually so hard, and scaled so bad.

like it includes a lot of concepts but not deep enough

if this is correct,
got variable capacitor wrong
got standard capacitor correct iirc
got diode correct iirc

welp barely said any of that lmao

what about the signal diode? also how did you do that waveform question? And also the impedance one?

same might of got like 3 max correct lol

my wave forms were bad i just know for one i did it in the positive direction DC [made sure it was in 1 direction only]
