Hi
1. Can you explain,the circuit,of OR gate, at the url:
http://www.technologystudent.com/elec1/dig2.htm
the picture with 2 BJT NPN transistors,
in the state of:input a=0,input B=0,
why the output is 0 ?
according to the circuit,the bulb should light,
because,there is a complete path from the 6+ volt ,
to the 0 volt.
2. Does that circuit, contains only one,voltage source,
or 2?
