In this worksheet, we will practice describing the time evolution of circuits containing inductors, capacitors, and resistors.

**Q2: **

In an oscillating circuit, ฮฉ, mH, and ยตF. What is the angular frequency of the oscillations?

**Q3: **

What resistance must be connected in series with a 200 mH inductor and a 12 ยตF capacitor for the resulting RLC oscillating circuitโs charge to decay to of its initial value in 40 cycles? Assume .

**Q4: **

In an oscillating RLC circuit, , , and . Initially, the capacitor has a charge of 8.0 ยตC and the current is zero.

Calculate the charge on the capacitor 10 cycles later.

Calculate the charge on the capacitor 60 cycles later.
