WebSimilar to the input impedance, you can vary the load resistance until the value you measure on point C is HALF of Vth, which implies this chosen load resistance is the SAME as Rth (or Zout). Congratulation, … Weboutput resistance is much more complex than determining the input resistance. The output resistance of an amplifier is the ratio of the amplifier’s open-circuit output voltage and its short-circuit output current: oc o out sc o v R i = Again, we determine these values by analyzing the small-signal amplifier circuit.

WebThe input impedance of an electrical network is the measure of the opposition to current (), both static and dynamic (), into the load that is external to the electrical source network. The input admittance (the reciprocal of impedance) is a measure of the load network's propensity to draw current. The source network is the portion of the network that … Web12. Measure the input impedance r. i. To do this, use the setup shown in the circuit diagram in Figure 7-2. Use the input signal from the function generator (100mVp-p @ 4kHz). 13.
