## Homework Statement

Full Wave Bridge Rectifier circuit

Basically this circuit, but ZL is r//c not simply r as it is in this circuit (also, disregard any values... just the model is relevant)

Vs=6.5cost(2pi60t)

CL=1μF

RL=500Ω

I'm trying to find Vmax and Vripple.

## Homework Equations

Vmax = Vdc-2Von

Vr = (Vmax Tau) / (2RC)

Tau = 1/f <-- This must be wrong but it's the only Time constant equation I have.

## The Attempt at a Solution

Vmax = Vdc-2Von = 6.5 - 2(.5) = 5.5v

Tau = 1/f = 1/60 = .0166

Vr = (Vmax Tau) / (2RC) = 5.5 * Tau / (2(500)(1x10-6) = 91.6

My output graph (generated using SPICE) shows a sinusoid from around .2ish to 5ish Vo so clearly 91 Vripple is wrong. There should be a Vripple of about 5v to achieve this specific Vo. I'm 95% that my error is in the Tau calculation but I just can't find any info in my book/web about it.

Any help is appreciated, ty.
