What is the unit of electric field?
The units of the electric field in the SI system are newtons per coulomb (N/C), or volts per meter (V/m); in terms of the SI base units they are kg⋅m⋅s−3⋅A−1.
What is the unit and dimension of electric field intensity?
[ML−1T3A1]
What is the formula of electric field lines?
The units of electric field are N/C. E = F q test = k | Q | r 2 . This equation gives the magnitude of the electric field created by a point charge Q. The distance r in the denominator is the distance from the point charge, Q, or from the center of a spherical charge, to the point of interest.
What are electric field lines?
An electric field line is an imaginary line or curve drawn through a region of empty space so that its tangent at any point is in the direction of the electric field vector at that point. The relative closeness of the lines at some place gives an idea about the intensity of electric field at that point.
What is the unit of electric field Class 12?
The S.I unit of electric field intensity is newton per coulomb.
What are electric field lines Class 12?
An electric field line is an imaginary line or curve drawn from a point of an electric field such that tangent to it (at any point) gives the direction of the electric field at that point.
What is the dimensional analysis of electric field?
∴ Dimensions of electric field are [MLT-3A-1].
How do you calculate field lines?
The field lines of a vector field F(x) = ∇u(x) in R2 that is the gradient of a scalar field can be drawn without solving a DE.
What is electric field lines Class 12th?
What are electric field lines Class 12 physics?
CBSE NCERT Notes Class 12 Physics Electric Charges Fields. Electric field lines are a pictorial way of representing electric field around a configuration of charges. An electric field line is a curve drawn in such a way that the tangent to it at each point is in direction of the net field at that point.
What is electric field and SI unit?
The value of the electric field has dimensions of force per unit charge. In the metre-kilogram-second and SI systems, the appropriate units are newtons per coulomb, equivalent to volts per metre.
