There could be various methodologies and formulas related to this distribution, but to simplify it for you, it is often denoted as the symbol lambda. Our first step is to define a charge density for a charge distribution along a line, across a surface, or within a volume, as shown in Figure 5.6.1. You can think of it as a fluid of charge. And the lambda is the charge density, or in this case, the charge per unit length, which would be in coulombs per meter, charge per unit length. Get subscription and access unlimited live and recorded courses from Indias best educators. The SI unit is Coulomb m-2. The charge distributed over a conductor length is known as the linear charge distribution (commonly known as the linear charge density). We can divide the charge density formula into three types depending on its nature: (i) Linear (ii) charge density ( ) (iii) Surface charge density ( ) (iv) Volume charge density ( ). Volume Charge Density: = q V where q is the charge and V is the volume of distribution. Therefore, denotes the charge per unit length or linear charge density. Where dq is a small amount of charge in small length dl. So this is the reality over here. Let's draw it on the board, really large, okay. The direction of the electric field is perpendicular to the line of charge. So the electric or the negative charge is smooth all the way down to the smallest scale that you could have, infinitely small scale. Here, we characterize it with lambda. So we don't like to do that. Really, the question is, on the scale that we're going to calculate, if it's, say tens of centimeters, is the charge smooth on that scale? And if it is, and it's a good model. If we were going to try to calculate the electric field of those electrons, it would be really hard. The SI unit will be Coulomb m-1. document.getElementById( "ak_js_1" ).setAttribute( "value", ( new Date() ).getTime() ); This site uses Akismet to reduce spam.
