I have attached two circuits..
One is an led driver using npn transistor and other one is led driver using a resistor..
I wanted to know what is the difference..
If i will not use the transistor and use just the resistor what is the harm?
I just want if my AND gate output is 1 the led should glow else not glow.
The transistor is behaving like a switch or amplifier?
I am confused coz transistors always confuse me..
