530. Problem 38.67 (RHK) We have to find the resistance R that should be connected
to an inductor

Solution: Click For PDF Version In a LCR circuit the variation of charge as a function of time is given by the function in which
The inductance in the circuit is
and the capacitance in the circuit is
Therefore, the period of LC-oscillations will be We want to fix the resistance in the LCR-circuit in order that the maximum charge on the capacitor decays to 99% of its initial value in 50 cycles, that is in We have the condition
