a simple basic question
hey guys
i want to know why do we use biasing resistors in BJT. i mean i common emitter mode for example, we use a resistor with in series with base
whats the reason for this. someone in class said that its because we cant directly connect 5 volts to a transistor. i couldnt digest it because if we cant do it then why is emitter connected without a resistor to same voltage source. so this reason was definitely not right
can anyone tell me the real reason as i am kinda stuck at it. the teacher keeps on saying its necessary for biasing but doesnt tell how and why
