Discrete Charge Distribution The electric field created by the two charges will turn out to be the sum of the electric fields created by each one. This works for any number of given charges (a thousand, a million, even a billion). The arithmetic gets messier, but the idea stays the same.

What is discrete nature of electric charge?
The discrete nature of electricity means that, it’s strength depends on amount of electrons it carries, if it carries 1e or 5e or 10e in each case the nature(i.e. strength) of electricity will be different.
Why is charge discrete in nature?
Charge on a body is an integral multiple of the smallest unit of charge I.e electronic charge. Thus charge is said to have discrete nature and said to be quantised.
Is electricity discrete or continuous?
Electric charge, which can be positive or negative, occurs in discrete natural units and is neither created nor destroyed. Electric charges are of two general types: positive and negative.
What does discrete mean in physics?
Discrete in science is the opposite of continuous: something that is separate; distinct; individual. Discrete may refer to: Discrete particle or quantum in physics, for example in quantum theory.
Is wind speed discrete or continuous?
A wind speed and atmospheric pressure of 40.52 mph and 1000.23 mbar are perfectly reasonable values, so fundamentally, these are continuous variables. Notice that even though pressure is continuous variables it looks like a discrete variable because it has only been measured to the nearest whole millibar.
What are the 3 types of charges?
Examples of the types of charges are subatomic particles or the particles of matter: Protons are positively charged. Electrons are negatively charged. Neutrons have zero charge.
What is the difference between discrete and continuous data?
Discrete data is a numerical type of data that includes whole, concrete numbers with specific and fixed data values determined by counting. Continuous data includes complex numbers and varying data values measured over a particular time interval.
Why can a Gaussian surface not pass through any discrete charge?
The Gaussian surface doesn’t pass through any discrete charge. This is because electric field due to a system of discrete charges is not well defined at the location of any charge. However, the Gaussian surface can pass through a continuous charge distribution.
What is discrete nature?
adjective. 1. Distinguished from others by nature or qualities: distinct, separate, several, various.
What is a discontinuous charge distribution?
The electric field due to a discrete charge configuration is not defined at the locations of the discrete charges. For continuous volume charge distribution, it is defined at any point in the distribution. For a surface charge distribution, electric field is discontinuous across the surface” meaning.
What is continuous charge?
In a continuous charge distribution, all the charges are closely bound together i.e. having very less space between them. But this closely bound system doesn’t mean that the electric charge is uninterrupted. It clears that the distribution of separate charges is continuous, having a minor space between them.
Are electric field lines discrete?
For example, the field lines drawn to represent the electric field in a region must, by necessity, be discrete. However, the actual electric field in that region exists at every point in space.
Is temperature discrete or continuous?
Because body temperature is a continuous variable with many possible values, we summarize its distribution by reporting statistics such as the median, minimum, maximum, mean and standard deviation.
Can discrete data be infinite?
Discrete data can be seen and easily determined. This also means that it cannot occupy an infinite number of possibilities. Instead, it can occupy one of a series of numbers on a range.
What’s the difference between discreet and discrete?
Discrete means “separate,” while discreet means “unobtrusive.” Both words have the same etymology coming from the Latin discretus which means “to keep separate” or “to discern.” An easy trick to tell them apart is to remember is that the “e’s” are separated by the “t” in “discrete.”
Is physics discrete or continuous?
Current physics is, as stated by other answers, based on fully continuous mathematical models, which particularly assume spacetime to be continuous. On the other hand you could argue that these models are isomorphic to discrete constructive models, with the general view that the continuous is the limit of the discrete.
What does discrete mean in quantum?
The word quantum refers to discreteness, i.e., the existence of individual “lumps” as opposed to a continuum. In Newtonian physics, all quantities are allowed to be continuous. For instance, particles can have any momentum and light can have any frequency.
Is age discrete or continuous?
Mondal[1] suggests that age can be viewed as a discrete variable because it is commonly expressed as an integer in units of years with no decimal to indicate days and presumably, hours, minutes, and seconds.
What are 5 examples of discrete data?
- Ticket sales.
- Products sold in a month.
- Number of employees.
- Number of reviews for a specific product.
- An employee’s hire date.
- Bar graphs.
- Frequency tables.
- Plotted points.
Is price discrete or continuous?
Price is a continuous variable because it can be scaled up and down. It lowest unit of measurement is, for example, a cent. Even other continuous variables have lowest units of measurement, not just price.
Is human body positively charged or negatively charged?
Resting cells are negatively charged on the inside, while the outside environment is more positively charged. This is due to a slight imbalance between positive and negative ions inside and outside the cell.
What is the SI unit of charge?
coulomb, unit of electric charge in the metre-kilogram-second-ampere system, the basis of the SI system of physical units. It is abbreviated as C.
Is energy a charge?
Charge is wave amplitude at a given distance (r). It can be expressed as energy, but it is often expressed as a force, known as Coulomb’s law. The Coulomb constant is the magnetic constant times wave speed squared, over 4ฯ.
Is eye color discrete or continuous?
Examples. The following are examples of discrete variables: Gender. Eye color (brown, blue, green, hazel)
