Volume Charge Density Formula

In electromagnetism, the charge density tells how much charge is present in a given length, area or volume. The greek symbol Pho $\left(\rho\right)$  denotes electric charge, and the subscript V indicates the volume charge density.

The charge in terms of volume charge density is expressed as,

$\huge \rho =\frac{q}{v}$

Where,

 is the charge density

q is the charge(C)
v is the total volume in $m^{3}$.

Volume Charge Density Solved Problems

Question 1: Find the volume charge density if the charge of 10 C is applied across the area of $2\,m^{3}$.

Solution:

Given:
Charge q = 10 C
Volume v = $2\,m^{3}$.

The volume charge density formula is,

$\large \rho =\frac{q}{v}$

$\large \rho =\frac{10C}{2m^{3}}$

$\large \rho =5\,C/m^{3}$
