Refer to the circuit shown below containing a two-port network.
The two-port is a transconductance amplifier.The input port of the two-port is defined by terminals A and B. The output port of the two-port is defined by terminals C and D.Given: R1 = R3 = 1 k_, R2 = 100 k_ and k = 0.1 A/VFind the following:a) The equivalent two-port amplifier model.b) If V1 = 1 V, find the current through the load Io if the load is a loadresistance RL = 100 k_.
Q. A three-phase load, connected to a 440-V bus, draws 120 kWat a power factor of 0.85 lagging. In parallel with this load is a three-phase capacitor bank that is rated 50 kVAR . D

Q. Why positive feedback is used in oscillator? The main application of positive feedback is in oscillators. An oscillator generates AC output signal without any input AC signa
Q. Explain the effect of feedback on amplifier bandwidth? The bandwidth of an amplifier is defined as the range of frequencies for which the gain remains constant.The gain -ban
Q. Show Maximum Common-Mode Input Voltage of amplifier? This is the maximum voltage that the two inputs can be raised above ground potential before the op amp becomes nonlinear
Q. D flip-flop - latch or delay element? The symbol for the clocked D flip-flop is shown in Figure (a), in which the two output terminals Q and ¯ Q behave just as in the SRFF,
Q. Explain the significance of the Coupling capacitor and the RE - CE circuit. The function of the coupling capacitor is to isolate the amplifier input circuit from the source.
