I am very new to electronics field. Especially to the digital electronics.
I am trying to make an AND gate circuit using transistors, switches and LED. I have tried the below circuit:
But there is a problem when simulating this circuit.
SW1 | SW2 | LED OFF | OFF | OFF OFF | ON | 80% ON | OFF | 20% ON | ON | 100%
As you can see that above mentioned truth table is not AND Gate but it looks more like OR Gate. So, what is my mistake??
