That's the one but...
How is he getting 170 volts out of a 120? I checked across my bridge output and am getting DC reading of 108 volts. Hence my caculation:
120vac/bridge/108 VDC
(4) x 3.5 (leds) = 14 (series)
108 - 14 = 94
94/0.020 (led rated current) = 4700 = 4.7K
94 x 0.02 = 1.88 (I'm using a 2 watt metal oxide flame resistant)
I've read about how a full wave rectifier works but cannot figure out how 120 volt peak to peak (not rms) sine wave is converted to 170 volt peak to peak pulsating DC.
I really do want to learn why and how. Fortuntely, where these are going to be placed I have to worry about the deer munching the plastic.
Than you for the help. I do appreciate it.
Respectfully,
Jeff
