Here's a very useful schematic from "The Art of Electronics Student Manual"
Using the following mathematics,
we basically proved that a circuit using a only a capacitor and resistor can be used as an "integrator" (which is way cooler than what your TI-83 graphing calculator can do), as long as V-out stays small. I used a function generator, to create various Vin signals (left), which I ran through my "integrator" (right)
sine wave:
square wave:
triangle wave:
Pretty Neat Huh?
Lab / Questions for "Tuesday 12th" on capacitors:
Lab 2‐1 in the Student Manual (An RC circuit, experimentally)
500 kHz square wave, time for output to drop 37% =100 mirco seconds
time for output to rise 63% 100 micro seconds. R=10k, C=.01uF, RC = 1x10^-4 = 100us Works!
Build a "Cap-meter" with picoblocks program
My cap-meter caps / outputs
1 x 0.1uF capacitor === 11
2 x 0.1uF in parallel === 22
2 x 0.1uF in series === 5
In parrallel the capacitors have to charge one after the other, but in parallel, the current can travel the path of least resistance. The results make sense.
