An oscillating cirucuit consits of capacitance `C=10 mu F`, inductance `L=25 Mh`, and active resistance `R=1.0 Omega. ` How mancy oscilaltion periods does it take for the current amplitude to decrease e`-` fold ?

Text Solution

Verified by Experts

Current decreases `e` fold in time
`t=(1)/(beta)=(2L)/(R) sec=(2L)/(RT) ` oscillations
`=(2L)/(R)(omega)/( 2pi)`
`=(L)/(piR)sqrt((1)/(LC)-(R^(2))/(4L^(2)))=(1)/(2pi)sqrt((4L)/( R^(2)C)-1)=15.9` oscillations
