An inverting amplifier is built using an opamp that has a 2V internal offset voltage. (You may consider the opamp ideal otherwise). The circuit uses a feed-back resistor of 2K and an input resistor of 1K. If a 2V input is given to the amplifier, what will be the input resistance seen by the 2V input source.
The expression for the torque of an induction motor as a function of its slip may be obtained by application of Thevenin's theorem to the circuit model. Show that the Zth obtained can be shown to be approximately equal to Zth = R1+JX1
An ideal p-n junction diode has saturation current Is = 3e-15 A. Calculate the diode current.
A box of mass 20kg is slid down a ramp inclined at 20 degree with an initial speed of 5 m/s. If the box stops after 10 m, what was the coefficient of kinetic friction between the box and the ramp
Write a program to find the sum of the elements of an array called list1. The size of list1 is four bytes. The values of list1 are $FF, $1, $FE, and $02. To check your work, the sum should become $0200.
Each of the four members of a "jukebox jury" is provided with a pushbutton; the button is pressed if the record played is a "hit" and is not pressed if the record played is a "miss". Design a digital logic system that lights a lamp
In a typical commercial electrical distribution system, which is more common: an inductive power factor, or a capacitive power factor. What is the most common technique used to correct this kind of low power factor.
