Hey guys let say i have 2 leds in Parallel ... and 2 other leds in series...
If i supply 20mA to the both sets... will this be true:
A. 2 in parallel will take up 20mA(40mA) each (hence the need for 2 resistors)(but require less voltage overhead) (VDROP)
B. 2 in series take up only 20mA since in series.(require more voltage)(Vdrop *2)
hi atom,
Each parallel LED will take 20mA, assuming both have their own resistor
In series 20mA total.
What are the LED colours and whats your supply voltage?
