Homework Statement
I'm specifically having trouble with taking the Fourier transform of f(t) in order to sketch F(w) and also to move on with the rest of the problem.
Homework Equations
f(t) = (5+rect(t/4))cos(60pi*t)
mixed_signal = cos(60pi*t)
The Attempt at a Solution
I attempted to...
Ah, thanks technician. That makes sense now haha.
So I'm allowed to assume in a problem like this that all the capacitors in series have the same charge on them?
The equivalent capacitance is 3.415 μC, the potential energy in C2 is 95 μJ, and the voltage across C2 is 3.08 volts. That's all the information I've been able to derive.
Homework Statement
Four capacitors are connected as shown and connected to a battery to maintain a constant potential difference between points a and b. A charge Q2 = 61.6 μC is measured on capacitor 2.
What is the charge on capacitor C3?
Homework Equations
Q = CV; rules for...
