what is the maximum current peak-peak going to led. the schematic is given
br1 is bridge rectifier made of four 1n4007 diodes ---max forward voltage is 1000v and piv is 700v
ac supply is wrongly given 220 v it is actually 230v ( this is rms voltage) and freq is 50 hz
the resistors are of 30 k each.
will the led light at the current or not? max forward current for led is 60mA and minimum i dont know.
max forward voltage is 1000v
.
I seriously doubt that. Reverse voltage perhaps, otherwise you need at least 2000V to make sure the bridge conducts!
If the a.c. is the sine wave it should be, then the peak voltage is 230 x sqrt(2) which is 325V. Call that 320V for round numbers, and to allow a small drop across the diodes and LED. So 320V is dropped across two 30k resistors. By Ohm's Law this is 320V/60k = 5.3mA.
Will the led work at 5.3 mA?
