Finding Max and Min in Oscillating LRC Circuit

In summary, The oscillating LC circuit has an inductance value of 3.00 mg and a capacitance value of 2.70 * 10^-6. At t=0, the capacitor has no charge and the current is 2.00 Am. The maximum charge that will appear on the capacitor can be found using the formula Q_m=C*U_m, and the earliest time where the energy stored in the capacitor is the greatest can also be determined using this formula. To find the greatest rate, the problem can be set up using the given values and solved for the desired variable. Additional help and guidance can be found in the provided link.

In an oscillating LC circuit L = 3.00 mg and C = 2.70 * 10^-6. At t=0 the charge on the capacitor is zero and the current is 2.00 Am.

What is the maximum charge that will appear on the capacitor?
The earliest time where energy stored in the capacitor is the greatest?
What is the greatest rate?

Our teacher just barely touched upon finding the max and the mins in the oscillating of a LRC circuit. I haven't a clue even where to start. Could i get some help setting up the problem?

thanks a bunch. it was much easier than i thought. i finished the rest of the problem with ease. thank you!
 

1. How do you find the maximum and minimum values in an oscillating LRC circuit?

The maximum and minimum values in an oscillating LRC circuit can be found by analyzing the voltage or current across the capacitor or inductor. The maximum value occurs when the capacitor is fully charged or the inductor is fully discharged, while the minimum value occurs when the capacitor is fully discharged or the inductor is fully charged.

2. What factors affect the maximum and minimum values in an oscillating LRC circuit?

The maximum and minimum values in an oscillating LRC circuit are affected by the capacitance, inductance, and resistance of the circuit. A higher capacitance or inductance will result in higher maximum and minimum values, while a higher resistance will result in lower maximum and minimum values.

3. How do you calculate the maximum and minimum values in an oscillating LRC circuit?

The maximum and minimum values in an oscillating LRC circuit can be calculated using the equations Vmax = Imax X XC and Vmin = Imin X XL, where Vmax and Vmin are the maximum and minimum voltages, Imax and Imin are the maximum and minimum currents, and XC and XL are the reactances of the capacitor and inductor, respectively.

4. How does the frequency of the alternating current affect the maximum and minimum values in an oscillating LRC circuit?

The frequency of the alternating current has a direct impact on the maximum and minimum values in an oscillating LRC circuit. A higher frequency will result in higher maximum and minimum values, while a lower frequency will result in lower maximum and minimum values.

5. Can the maximum and minimum values in an oscillating LRC circuit be controlled?

Yes, the maximum and minimum values in an oscillating LRC circuit can be controlled by adjusting the values of the components in the circuit, such as the capacitance, inductance, and resistance. By changing these values, the frequencies at which the maximum and minimum values occur can also be altered.
