When we go to a hotel there we claim to bring two iddlies (ie one plate) or four iddlies. We cannot order for 2.5 iddlie or 4.2 iddlies. It is not allowed. This is what we call quantisation of iddlie. Same way nature has quantized the electric charge to be of a least value 1.602 x 10-19 C. It is denoted by the symbol 'e' which is the first letter of the word 'elementary'. Hence the charge of a body will be an integral multiple of this elementary charge and so q = n e, here n is an integer.
There by proton has one +e and an electron has one -e. In case of sodium atom there are 11 protons in the nucleus and 11 electrons outside of the nucleus. Hence the algebraic sum of the charges in this case of sodium atom becomes +11-11 = 0. Hence neutral.

What does quantisation of charge mean?
Quantization of charge means that the electric charge carried by an object is always a multiple of the elementary charge (the charge of a single proton or electron). This concept arises from the discrete nature of charge, which is one of the fundamental properties of matter.
What is quantisation of electric Field?
Quantization of the electric field refers to treating the electric field as composed of discrete packets of energy called photons. This is a fundamental concept in quantum electrodynamics, where the electromagnetic field is described in terms of discrete quanta rather than as a continuous wave. Each photon carries a specific amount of energy proportional to its frequency, and this quantization helps explain various phenomena such as the photoelectric effect and blackbody radiation.
Why do we ignore quantisation of electric charge when dealing with macroscopic charges?
We ignore quantization of electric charge at the macroscopic scale because the individual charges are so large in quantity that the discrete nature of charge at the atomic level becomes statistically insignificant and can be treated as a continuous distribution. This allows us to simplify calculations and models when working with macroscopic charges.
What was Einsteins his greatest invention?
Einstein wasn't really an inventor he was a theoretical physicist. Some of his greatest discoveries were general relativity, the quantisation of the photon and the mass energy equivalence equation (E=MC^2).
How did Niels Bohr's model of the atom different from Rutherford model?
first the positive and negative charges are separated on the models and technically speaking, niels bohrs is more advanced and more accurate. Bohr's atomic model was based on quantisation of energy and angular momentum of the electron whereas Rutherford does not give an idea of permitted orbits.
What do you mean by quantisation of charge?
The principle that the electric charge of an object must be part of a divisible basic axiom.
Sampling frequency doubles then quantization noise?
quantisation noise decrease and quantization density remain same.
Why do you get a staircase output in the quantization process of Pulse Code Modulation?
quantisation is the assigning the signal amplitudes to some levels,if amplitude is 4.8 we treat it as 5 and when it is 3.1 the output value is 3 thus we are assigning the amplitude to some reference levels thus corresponds to different amplitudes we get different quantisation output hence we get staircase signal
What is the relationship between quantisation noise and bandwidth in pcm systems?
Quantization noise is a model of quantization error introduced by quantization in the analog-to-digital conversion(ADC) in telecommunication systems and signal processing.

What does digital recording do to an analog sound wave?
It quantizes it into discrete points represented by zeros and ones (digital information). The number of samples must be at least two times the highest frequency component of the analog wave. The number of bits in each sample determines how close the digital information is to the actual value of the analog signal.
Why Q is used as symbol for charge?
charge means they considered some quantityAnswer:The letter Q is an arbitrary selection that was chosen, and has stuck. Just like the designation of Alpha, Beta, Gamma for various particles. It is an adopted convention.

What are advantages and disadvantages of digital signal processing?
Adv. Digital · easy to store and use, that is why computers use it. · Digital data is designed and artificially created, so it is efficient. · Less expensive . DSP is easier to reconfigure as it is made up of h/w as well as s/w. Disadv. Digital · Digital communications require greater bandwidth than analogue to transmit the same information. . Due to Quantisation , an error is alwz there.
How can the de Broglie wave concept be used to explain the Bohr fixed orbits of an electron in an atom?
In the case of Hydrogen, the Bohr model is equivalent to assuming that the electron forms a circular stationary wave when it is in a stable orbit.To see how this works, assume that the orbital radius is r, so that the circumference of the orbit is 2πr. For a stationary wave the wavelength must fit into this orbit a whole number of times, so if λ is the wavelength then we must haveλ = 2πr / nfor some integer n. Now, de Broglie says that the wavelength is related to the particle's momentum p via the equation λ = h/p, where h is Planck's constant. Combining this with the previous equation we can obtain Bohr's quantisation condition for the orbital angular momentum,pr = nh/(2π).Furthermore, since the electron moves in a circular path (in this model) the radial force must have magnitude mv2/r = p2/(mr), with m being the electron mass. Equating this to the Coulomb force and using the quantisation condition above we see thate2/(4πε0r2) = (nh)2/(4π2mr3)which gives us the formula for the orbit's radius:r = n2h2ε0/(πme2).The total energy (kinetic + potential) of the electron isE = p2/(2m) - e2/(4πε0r)which we can simplify using the previous formula and the quantisation condition again to obtain:E = -me4/(8ε02h2n2)(note the minus sign). This is the well-known formula for the hydrogen atom's energy levels, which we can also write asE = -hcR/n2with c being the speed of light and the Rydberg constant R being defined asR = me4/(8ε02h3c) = 10.974 x 106 m-1.
Summarize and interpret the experimental evidence for quantisation of charge?
Millikan's oil-drop experiment provided clear evidence for the quantization of charge, showing that the charge on an object is always a multiple of a fundamental unit of charge, e. The experiment measured the charge on oil droplets suspended in an electric field, demonstrating that the charges observed were all multiples of a single value. This confirmed the discrete nature of charge and led to the development of the modern understanding of the quantization of charge in particles like electrons.
