What is the unit of line integral of electric field intensity?


What is the unit of line integration of electric field intensity?

The physical quantity obtained by the line integral of the electric field is potential and its unit is JC−1. Potential is the energy per unit charge. The electric field is the region in which a charge applies force of attraction or repulsion on another charge.

What is the SI unit of integral of electric field?

Surface integral of electric field is electric flux and its unit is Nm2C1.

What is the unit of field intensity?

Joule/newton. Hint: The unit of electric field intensity can be found by using the units of force and charge, as electric field intensity is the force per unit coulomb. Mathematically, E=Fq, where E is electric field intensity, F is the force exerted on charge and q is charge.

Why is line integral of electric field zero?

Let us first assume two points a and b in an electric field due to charge q. Some amount of work is done to move a test charge from one point to another point along a closed path. … Hence, the line integral of a closed path will be equal to zero.

What is the dimension formula of electric field?

Or, E = [M1 L1 T2] × [I1 T1]1 = [M1 L1 T3 I1]. Therefore, the Electric Field is dimensionally represented as [M1 L1 I1 T3].

What is SI unit of electric flux?

Electric flux has SI units of volt metres (V m), or, equivalently, newton metres squared per coulomb (N m2 C1).

Which electric field is a physical quantity?

Electricity and Magnetism

Physical Quantity Unit
Electric Charge [Coulomb]
Electric Current [Ampere] = [Coulombs/second]
Electric Field [Newtons / Coulomb]
epsilon [Coulomb2 / meter2 / Newton]

What is unit of electric intensity?

The electric field intensity (volts/meter) at any location is the force (Newtons) that would be experienced by unit test charge (Coulombs) placed at the location.

What is electric intensity and its unit?

Definition- the electric field intensity is defined as the ratio of the force →F experienced by the charge and the amount of the charge q . ∴→E=→Fq. Force is a vector quantity. The SI unit of the electric field intensity is volt/meter or V/m.

What are two units of electric field?

The SI unit of the electric field is volts per meter (V/m). This unit is equivalent to Newton’s per coulomb. These are derived units where Newton is a unit of force and Coulomb is the unit of charge.

What is the unit of negative line integral of electric field?


What is electric potential equal to?

Electric potential, the amount of work needed to move a unit charge from a reference point to a specific point against an electric field. … The electric force F exerted by the field on the positive charge is F = qE; to move the charge from plate A to plate B, an equal and opposite force (F′ = −qE) must then be applied.
