how can i find input and output impedance of a ce amplifier- (voltage divider )..suggest practical methods?
Finding Input/Output Impedance of a CE Amplifier: Practical Methods
Click For Summary
To find the input and output impedance of a common emitter (CE) amplifier, begin by determining the small-signal hybrid-pi model parameters for the transistor. Next, write the Kirchhoff's Voltage Law (KVL) loop equations for both the input and output circuits, incorporating the biasing and hybrid-pi model. After establishing the equations, manipulate them algebraically to derive the input and output driving-point impedances. Practical methods include using voltage divider techniques to measure these impedances effectively. This approach ensures accurate impedance characterization for CE amplifiers.
I grabbed an under cabinet LED light today at a big box store. Nothing special. 18 inches in length and made to plug several lights together. Here is a pic of the power cord:
The drawing on the box led me to believe that it would accept a standard IEC cord which surprised me. But it's a variation of it. I didn't try it, but I would assume you could plug a standard IEC cord into this and have a double male cord AKA suicide cord. And to boot, it's likely going to reverse the hot and...
