Inverting Summing Amplifier
Fig shows inverting summing amplifier. It's a inverting configuration with three inputs VA, VB and VC. Depending on the relationship between feedback resistor RF and input resistors RA, RB, and RC, circuit can be used as a summing amplifier.
Work out the voltage for the following arrangement of 1.5V cells: ( Solve problems with cells in series, parallel and series-parallel)
Q Calculate the longest wavelength that can be analysed by a rock salt crystal of spacing d = 2.82 Ao in the first order. Data: d = 2.82 Å = 2.82 × 10-10 m; n = 1 ; λmax = ?
Q. What is Fresnel diffraction? a) The source as well as the screen are at finite distances from the obstacle producing diffraction. b) The wave front suffer diffraction is
a body travelling with uniform acceleration crosses two points A &B with velocities 30m/s & 50m/s the speed of the body at mid point of A&B is approximately?
Working: When plate potential (V p ) is positive, plate current ( I p ) flows in the circuit (because some emitted electrons reach to plate). If + V p enhances I p also increas
Determine the real position of an air bubble in a glass cube of side 0.3m if the bubble seems to be at a distance of 0.05 m from one face and at 0.15m from the opposite face.
Explain the acoustic cavitation. Acoustic Cavitation: Usually, cavitation is the phenomenon where largely and small empty cavities are generated into fluids that expand to l
Organic & polymer solar cells are made from thin films (typically 100nm) of organic semiconductor such as polymer and small molecule compounds like poly phenylene vinylene, copper
It is known that the pressure developed by a centrifugal pump, Δp, is a function of the diameter D of the impeller, the speed of rotation n, the discharge Q, and the fluid density
