(adsbygoogle = window.adsbygoogle || []).push({}); 1. The question.

Suppose that the input frequency into a full-wave diode bridge rectifier is 60Hz, and suppose that the RC time constant of the network filter capacitor and the load resistance is 10ms.

Estimate the time after the peak input voltage when the diode shuts off.

The circuit looks like this:

2. Relevant equations

I have no idea where to start. I do know that the ripple voltage equation for full wave rectification is:

[tex]\Delta V = \frac{I_{load}}{fC}[/tex]

3. The attempt at a solution

I know that after the voltage hits it's peak value, the voltage decays at both the rate of discharge of the capacitor and the sinusoidal input. I also know that I have to find the time it takes for the decreasing rate to become dependent only on the discharge of the capacitor.
