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.
A bat emits a sound whose frequency is 142 kHz. The speed of sound in air at 20.0°C is 343 m/s. However, the air temperature is 35°C, so the speed of sound is not 343 m/s. Find the
Why does the charge on the outer surface of a parallel plate capacitor doesn't change when it is connected by a battery. only inner surface charge gets affected. Why??

50 gm of an optically active substance is dissolved in 100 ml of water. A plane polarised light, when passing through 30 cm of the solution, suffers a rotation of 390 in it's plane
Q. The kinetic energy of an electron 120 eV. Compute the de Broglie wavelength of electron. λ = h / √2mE λ = 6.626 X 10 -34 / √ 2 X 9.1 X 10 -31 X 120 X 1.6 X 10 -19
A parallel plate capacitor has nineteen interleaved plates each 75mm by 75mm separated by mica sheets 0.2mm thick. Assuming the relative permittivity of the mica is 5. Calcu

Melting point: 525 0 C. It has small band gap and very high mobility around 70,000Cm 2 /V-Sec. It has much easier to prepare in single crystal from the Gallium arsenide. It is
Like the centre of mass, the moment of inertia is a function of a body that is concurrent to its mass distribution. Moment of inertia gives a measurement of the resistance of a bod
