What are the limitations of transmission electron microscope?
Limitations of transmission electron microscope:
a. In TEM, the materials need extensive sample preparation; we require producing a sample thin sufficient to be electron transparent.
b. This is a time consuming process
c. The structure of the sample may be changed throughout the preparation process
d. The region of analysis is much small, the possibility which the region analysed may not be characteristic for the complete sample
e. The sample may be damaged through the electron beam, mainly in the case of biological samples.
With the help of a circuit diagram, explain how regenerative feedback is provided in an Hartley oscillator?
describe and explain the operation of a transformer
Explain physically how a p-n junction functions as a rectifier. Ans: When a P-N junction diode is forward-biased and applied voltage is increased from zero, hardly any current
Q. A capacitor of capacitance 2 μF is in an ac circuit of 1000 Hz. Compute the reactance of it. Solution: Capacitive reactance XC = 1 / ω C = 1 / 2π ν C =
A particle with mass m = 2:5 is moving along a straight trajectory. The distance covered by a particle is described by the function S(t) = t 3 + 2t 2 , where t > 0 is the time
Find the value of g by free fall method.
DC high-current measurement: In common with many simple multimeters, both analogue and digital, the high current range (e.g. 10A) is not only selected using the range selector
how can we conclude whether at some time interference will take place or not with the help of the concept of temporal coherence?
A car of mass 1600 kilograms (kg) was travelling at 30m/s when the brakes were applied and produced a constant retarding force of 8000 N (Newtons) to the car: Find - a) How far the
a) Here temperature difference of junction is used to produce thermo e.m.f. and vice-versa. b) This effect produced when junctions of a thermocouple are kept at dissimilar tempe
