graphical representation of electric fields.
When a tangent is drawn at any point on electric field line then that tangent gives the direction of electric field at that point so the electric field line represents the elec tric field.
the tangent to the line is in the direction of?E???at that point
When a tangent is drawn at any point on field line then that tangent gives the direction of electric field at that point
a pair of electric charges of equal magnitude q but opposite sign, separated by a distance
Dipole is a combination of two equal and opposite charges separated by a very small distance.
is from negative to positive charge
Dipole Moment? It is a vector quantity and is directed from negative charge to positive charge along the axis. It is denoted as and is defined as the product of the magnitude of either of the charge and the dipole length i.e.?p??=q(2l??)
Is a measure of the flow (in analogy with flow of fluids) of electric field through a surface.
Flux?It means flow?Electric Flux?The number of electric field lines passing through any area normally known as electric flux. It is given by??=E?area?flux is a scalar quantity
