Hello, I am an electrotech student stuck on an equation which I am unsure of. We are presently on the Power Supply Filtering, rectification topic, converting AC to a DC using 4 diodes. We also learn't that by adding a capacitor, we are able to hold the peak AC value with minimal lost, this is called the ripple effect. However, in our textbook we are given this formula Vrpp=(T*Vdc)/(Rl*C). Our teacher told us to use the peak value Vm so the equation becomes Vrpp=(T*Vm)/(Rl*C). What is the correct formula for Voltage ripple peak to peak, Vrpp?
