Logan's notes
Mostly talking about parallel vs series circuits. Covered Kirchhoff's voltage & current laws.
His voltage law:
where v = Volts,
v1 + v2 + v3 + ... + vn = 0
That is to say, once you calculate all voltage modifiers (power sources and resistors V = I*R), their sum should be equal to 0.
His current law states that all current branching from a wire is equal to the current present in the wire immediately present to the branch:
Let I = Amps:
I2 + I3 +I4 = I1 where I2, I3, and I4 are the branches from I1.
Parallel Resistance is calculated by taking two of the resistors, naming one R1 and the other R2, the solving (R1*R2)/(R1+R2). if more then two resistors are present, you can generalize the first two as R1 once you solve them and then move onto the next resistor. How the amps split in each node can be calculated using Ohm's Law (in the I = V/R form, where R is the resistance present in each branch). The high potential of the circuit (voltage) doesn't drop until it hits resistance, so the voltage that goes into each branch in equal to the voltage immediately before the branch, but after the resistors it drops.
Resistors in Series simply stack resistance: 200R in series with 350R mean you have a total of 550R when running voltage through them.
