Linear Charge Density
The linear charge density is defined as the amount of charge present over a unit length of the conductor. It is denoted by the symbol lambda (λ). Its standard unit of measurement is Coulombs per meter (Cm-1) and the dimensional formula is given by [M0L-1T1I1].
Its formula equals the ratio of charge value to the length of the conducting surface.
λ = q/l
where,
- λ is the linear charge density
- q is the charge
- l is the length of surface
Charge Density Formula
Charge density refers to the amount of electric charge per unit volume or unit area in a given region of space. It is a measure of how densely electric charge is distributed within a material or a region.
To understand charge density, we must first understand this concept of density. The density of an object is defined as its mass per unit volume. Similarly, depending on the type of continuous charge arrangement, we can think of charge density as charge per unit length, surface, or volume.
