Problem 1
Given: 2 capacitors in a series, each capacitor's farad & voltage across.
Voltage uncertainty 1%, capacitor uncertainty 5%
C1: 1019microFarads C2: 553microFarads
V1: 3.58 volts V2: 6.56 volts
Uncertainty: 5% for CAPs & 1% for Volt
Find Q for each: Q1=3648 Coulombs Q2=3627 Coulombs
Find Q's +/-(variance): SQRT(.05^2 + .01^2) = .051
Q1 Variance: 186 Q2 Variance: 185
Now for the question:
find Q.total Q.total=C.eq * V.total => 3634.84
What is the Uncertainty of Q.total??
Does anyone know how to find Q.total's variance?
I've looked through my text and online, still no luck.
If anyone could make a suggestion, I'd be very appreciative.
Thanks
