Consider the transconductance amplifier shown in given Figure. Assume the op-amp is ideal.
(a) Derive the expression for the transconductance function Ag f = Io/Vi.
(b) If the circuit is designed such that RF /R1 = R3/R2, show that Io/Vi = -1/R2.
(c) Design the circuit such that Io/Vi = -0.5 mA/V.
A dc power distribution cable has two #6 copper wires. The copper wire table in the textbook lists each wire as having resistance of Ro=.4028 ohms per thousand feet at temperature of 25C. The temperature coefficient of copper is alpha=.004 per C.
Given an AC input voltage of Vrms = 200Vrms and a sinusoidal frequency of omega = 120pi rad/sec, determine the following: V1peak (peak value of AC input voltage) V1(peak-to-Vpeak )(peak to peak value of AC input voltage) Frequency of input voltage V..
The sending-end voltage is always adjusted so as to maintain the receiving-end voltage fixed at 220 kV. Using the power-circle diagram constructed for Prob. 6.12, determine the sending-end voltage and the reactive power supplied by the synchronous..
Find the most economical area of X-section of the conductor. Given that the density of copper is 8.93gm/cm3 and its specific resistance is 1.73 x 10-8 Ω m.
A self-excited DC shunt generator is delivering 20 A to a 100-V line when it is driven at 200 rad/s. It is known that Ra=1.0 ohms and Rf=100 ohms. When the generator is disconnected from the line, the drive motor speeds up to 220 rad/s
