(6 cards)
1
Q
W=
A
1/sqrt(LC)
2
Q
Current acrossinductor starts out as what? What about the charge on the capacitor initially?
A
Starts positively charged with no current flow and then increases in current flow and decreases in charge
3
Q
Whats pe for electric fields? Magnetic fields?
A
Magnetic: 1/2 LI^2
Electric: 1/2 C(deltav)^2
4
Q
Equation for charge WRT time
A
Q(t)=Acos(wt), A is an arbitrary scale factor
5
Q
Total energy:
A
(Q0^2)/(2C)
6
Q
What is dI/dt for an LC circuit?
A
d^2Q/dt^2
