How soon does the current amplitude in a...

How soon does the current amplitude in an oscillating circuit with quality factor `Q=5000` decrease `eta = 2.0` times if the oscillation frequency is `v=2.2 MHz`?

Text Solution

Verified by Experts

`Q=(pi)/(betaT)` or `beta=(pi)/(QT)`
Now `beta t=1n eta` so` t=(1n eta)/(pi)QT`
`=(Q1n eta)/(piv)=0.5ms`
