Hi,
I am using BC337 which is capable of driving 800mA load, i am using 9V 2A power.
The Load is LED connected to collector of BJT when i connect 110ohm 2Wattt Resistance it get Hot slowly and the brightness is also low. i need more bright LED and 20K variable R at the base from Vcc of 5V.
so, i need to know all LED of Red colour are connected in Parallel with each other there are ~250 LED
please tell how to increase the intensity of light from Led without changing the circuit of LED..?
