Is an electric field continuous or discrete?

The electric field is a map of the force that would be felt at any location by a +1 coulomb test charge. The charges creating the field can have a discrete distribution or a continuous distribution.

Is electric field lines are continuous?

Yes, the electrostatic field line is a continuous curve because a unit charge always experiences a continuous force when it is placed in an electrostatic field.

Why electric field lines are continuous and open loop?

If the electric field lines form a closed loop, these lines must originate and terminate on the same charge which is not possible because electric field lines always move from positive to negative. Therefore, we say electrostatic field lines never form closed loops.

How do we determine the electric field due to a continuous charge distribution explain?

If a charge distribution is continuous rather than discrete, we can generalize the definition of the electric field. We simply divide the charge into infinitesimal pieces and treat each piece as a point charge. Note that because charge is quantized, there is no such thing as a “truly” continuous charge distribution.

Is electric charge continuous?

In electrostatics, we usually consider charge to be continuous on any body, to calculate the electric field of the body.

What is the difference between discrete and continuous?

The key differences are: Discrete data is the type of data that has clear spaces between values. Continuous data is data that falls in a constant sequence. Discrete data is countable while continuous — measurable.

Is electric lines of force continuous or discontinuous?

Electric field lines are continuos curves. They start from a positively charged body and ends at a negatively charged body. No electric lines of force exist inside the charged body. Thus electrostatic field lines are continuous but do not form closed loops.

Does electric field lines form Closed Loop?

An electrostatic field line never forms a closed loop.

Why do electric field lines do not cross each other?

The direction of electric field line generally changes from point to point and hence are curved lines. And this implies two directions of electric field intensity at the point of intersection, which is not possible. Hence, two field lines never cross each other.

How do you find the electric field of a line charge?

The electric field surrounding some point charge, Q is,

1. E = 1 4 π ϵ 0 Q r 2 E = \dfrac{1}{4\pi\epsilon_0}\,\dfrac{Q}{r^2} E=4πϵ01r2Q.
2. d E = 1 4 π ϵ 0 d Q r 2 dE = \dfrac{1}{4\pi\epsilon_0}\dfrac{dQ}{r^2} dE=4πϵ01r2dQ.
3. d E = 1 4 π ϵ 0 μ d x r 2 dE = \dfrac{1}{4\pi\epsilon_0}\,\mu\,\dfrac{dx}{r^2} dE=4πϵ01μr2dx.

What is continuous charge distribution formula?

λ = dq/ dl. The unit of the linear load density is C / m. If we find a conductor with a length of ‘L’ with a surface load density of λ and take an aspect of dl on it, then a small charge will be on it. dq = λ dl.

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.

Can electric field lines be discontinuous?

Electric field lines canbe discontinuous. Consider an infinite sheet of uniform charge density. The field is constant on either side of the sheet, but abruptly switches direction when moving from one side to the other. The field is discontinuous at the location of the sheet.

Where do electric field lines originate and terminate?

Electric field lines either originate on positive charges or come in from infinity, and either terminate on negative charges or extend out to infinity. The number of field lines originating or terminating at a charge is proportional to the magnitude of that charge.

How do scientists know the electric field is everywhere?

So, given any charge distribution – discrete or continuous – scientists can do a bunch of math and find out exactly what the electric field is everywhere. All electric charges exert forces on one another. The electric field is a map of the force that would be felt at any location by a +1 coulomb test charge.

What is meant by continuity of electric field?

Continuity of electric field means that the field is continuous over a region and it does not change abruptly.
