1. Homework Statement
my teacher wants me to design a circuit to control the on or off of 4 BJTs in the circuit.
so i tryed to control a BJT at once .. it workshttp://user.qzone.qq.com/259234914/infocenter#!app=4
but there were somewrong with control 2 bjt in the circuit .. the BJT can not work whatever i put the value of resistance in the circuit .http://user.qzone.qq.com/259234914/infocenter#!app=4
