My goal is to flash a few white LED in serial using 9V battery.
Here are the specifications of this LED.
As I saw the Forward Voltage is 3.4V, but what does it really mean?
Can't I plug this LED into more than 3.4V battery without using resistor?
Also I know that max current of this 10mm LED is 300mA.
As I know during serial connection voltage is trying to split to each LED equally. But in parallel connection voltage is the same to each LED and current is growing up!
So tell me can I flash a few 10mm white LED without using a resistor?
If I can.. then tell me how many LEDs should I use?
So what is a solution?
