The graph in your problem is showing the position of the bus as time passes.
Think about how the position is changing as time moves on, or possibly over specific intervals of time.
Imagine the position line was going across the graph completely horizontally. That would mean the position isn't...
Alrighty. I guess my mind totally drew a blank around that capacitance. :blushing:
I feel a lot better about the frequency now; I'm hoping the others are okay, too.
1) Calculate the resonance frequency for this circuit.
ω_{o} = \frac{1}{\sqrt{LC}}
L = 20mH = 0.02H; C = 250x10^{-6}F...
Homework Statement
An RLC circuit has L = 20mH, R = 20kΩ, C = 250μF.
1) Calculate the resonance frequency for this circuit.
2) For a frequency ω=400 rad/s, determine the phase angle and the circuit impedance.
3) Using ε = 30[V]sin(ωt), calculate the current in the circuit. This will be a...
