What resistance R should be connected in series with an inductance L= 220 mH and capacitance C= 12.0 mF for the maximum charge on the capacitor to decay to 99.0% of its initial value in 50.0 cycles?
In an oscillating LC circuit with C = 64.0 mF, the current is given by i= (1.60) sin(2500t+ 0.680), where t is in seconds, i in amperes, and the phase constant in radians. (a) How soon after t = 0 will the current reach its maximum value? What are (b) the inductance L and (c) the total energy?
After fully charging a 400 F capacitor to Qo= 8 C, an LC circuit is disconnected from its battery, when the energy stored in the capacitor is only one-fourth of its maximum value, what is the current through the inductor if L =0.03 H?
