Q. Can you explain Noninverting Amplifier?
It is called "noninverting" because there is no sign inversion. A typical circuit is shown in Figure. With a finite op-amp gain Ao,
Since the ideal op amp draws no current,
i1 = i2
Also, as seen from Figure,
v2 = vi
In equating Equations, one gets
which is the gain of an ideal voltage follower. The same result applies if R1 →∞ (i.e., open circuit) for any finite R2.
Dielectric Heating Dielectric losses occur in insulating materials. These are same as hysteresis losses in magnetic materials. When an alternating electric field is a
Q. For the circuit of Figure, determine and sketch i L (t) and vC(t) for inductance values of (a)3/4 H, (b) 2/3 H, and (c) 3/17 H. Note that the inductance values are chosen her
A 100kw,230v,dc shunt generator,with Ra=0.05,and Rf=57.5 has no load rotational loss(friction,wandage,core loss)of 1.8kw.compute a) The generator efficiency at full load.
Q. Do the following operations with 8 bit bytes, and indicate the condition of the overflow and carry bits. a) 10111011 + 00000011 b) 11101101 + 11111001 c) 11011011 + 110
Define Time and Shift Invariant? Time and shift invariant means that the system characteristics and shift do not change with time, i.e. the system output is independent of the
I want to know whether the circuits for both methods(linear polarization resistance and electrochemical impedance spectroscopy) are same or not?
The subsequent voltage-source multiplying DAC is to be utilized to convert the digital data stream "11" and "01" to an analog signal. It has 2-bit inputs and hence is capable of c
