Q. Show NPN Common Collector Amplifier?
The common collector amplifier, often called an emitter follower since its output is taken from the emitter resistor, is useful as an impedance matching device since its input impedance is much higher than its output impedance. It is also termed a "buffer" for this reason and is used in digital circuits with basic gates.
can you please briefly explain about significance of the word direction in vectors with some valid points
