An oscillating circuit consists of a capacitor with capacitance `C=1.2 nF` and a coil with inductance `L=6.0 mu H` and active resistance `R=0.50 Omega`. What mean power should be fed to the circuit to maintain undamped harmonic oscillations with volage amplitude acroos the capacitor being equal to `V_(m) =10 V`? |
| Answer» `lt P gt =(RCV_(m)^(2))/(2L)` . We get `lt P gt =5 mW.` | |
