How exactly do transistors amplify voltage? I read on a tutorial that
In the case of the transistor which is the output? The collector or the emitter? Lets say I have 10V going into the emitter and 5V into the base electrode which gives a difference of 5V at the output. How would the transistor amplify that 5V at the output?The difference amplifier has two inputs and one output.
It amplifies the difference between the voltages at the two inputs.
If the voltage on one input is 10 mV and 15 mV on the other then the difference is 5 mV.
If the amplifier amplifies by ten times then the output voltage will 5 mV times 10 which equals 50 mV.
