Hi,
Can everybody direct me why I have a sine wave across my inductor when I connect it into 5V DC? The power supply is regulated so why my scope is showing more that 5 MHz across the inductor when the inductor is in parallel with the DC voltage?
I got almost 550 KHz when I joined a 483 cap across the inductor too!!
I know something about LC resonance, but not sure if it works with DC sources too!!
Resonance occurs when the Xl = Xc, so and in this cause the resonance freq of the L and C is equal
