trying to build a DC supply using a zener regulator with
1k ohm load
1k ohm series resistor
3300uF cap
1n4728a zener diode
x4 1n4002g rectifier diode(0.58V threshold)
12V secondary
schematic
in the load with 1k ohm resistor i'm getting 2.6V, and 0.26mA current(is this current too low?) then i changed the load resistor to 100ohm and the current didn't even buldge it is still 0.26mA.
isn't the load current supposed to be I = V / R? so my load current with 1k ohm resistor should be 2.6/ 1000 = 2.6mA, not 0.26mA like what i'm measuring.
