The second equation I listed is for driven circuits, this one isn't driven. Thanks, I see where that's coming from now. Keeping track of the voltage across the capicitor, the current leads the voltage by a certain phase depending on the impedance. Calculating the frequency of this circuit I...

The current is oscillating back and forth between the capacitor and inductor, the resistor damps the the voltage. When the impedance for the inductor and capacitor are the same, maximum output of voltage is attained. If max voltage is outputted, this is also the point where maximum current is...

To derive the second equation you need an RLC circuit, and for the first, well, it can be just an LC circuit or the resonance frequency of an RLC circuit, so I would use the second equation.

Also, I'm trying to avoid the plug and chug approach but I can't seem to find any similar problems to this to get a full understanding of both equations. I know that the first involves the resonance frequency, and the second involves the damping frequency, logically, I'd assume they're asking...

I know where the derivations are coming from, and I know how it also relates to damping force and all the good stuff involving second order differential equations, however this is where I'm confused. I do see what the equation is telling me, and you're right, the amplitude of whatever equation...

Homework Statement A certain circuit has a resistance of 30 Ω, inductance of 5.0 mH, and capacitance of 0.375 µF. At time t=0, the capacitor is charged with 4.0 µC on the top plate (and -4.0 µC on the bottom), and the switch is then thrown so that the capacitor can discharge through the...

Sorry, the text field isn't easy to work with as its my first time. The symbols in that equations correspond to N = to number of turns in the coil per meter Φ = to the magnetic flux of the solenoid I = to the current in the loop Mutual inductance can be calculated by using the current in the...

Homework Statement A long solenoid has a radius of 3 cm, 3000 turn per meter, and carries a current I = IOcos(ωt), where Io is 0.25 A and ω is 628 s−1 . It is placed through a circular loop of wire, radius 5 cm, which has resistance 100 Ω. The magnetic field in a solenoid is B = µonI. (a) Find...
