In the field of electromagnetism Current Density is the measurement of electric current charge flow in amperes per unit area of cross-section m 2.
. This is a vector quantity. Therefore the current density is dimensionally represented as M0 L-2 T0 I1. Current density is the rate of current flowing per unit area.
Current has two types. Current density is a vector quantity. The dimensional formula of current density is as follows.
Current Density Formula is j ρv j ρ v where j electric current density v velocity of charges ρ ρ charge density. Equation of continuity Then the probability current density can be defined as Re 1 2 mi mi J since 2 2 1 Re 1 mi m i i m i J Note-1 What is the units of. Current Density Formula The formula for Current Density is given as J I A Where I current flowing through the conductor in Amperes A cross-sectional area in m 2.
M 0 L -2 T 0 I 1 where M stands for the standard unit mass I stands for current L indicates the length and T represents the time. Formula for Current density The current density formula is as follows. The current dimensional formula for density is M 0 L -2 T 0 I 1.
J I AJ IA A m² A m² A m² A m² Variables J Current. AC and DC The flow of charge in a. J I A I A Current Density is represented by.
J IA where J is the Current. The formula of the current density is represented by the equation given below. Its magnitude is equal to the.
The current density J 4 ampere m 2. Current density formula J IA. Current density J Enter the unknown variable value as x Current density J Am2 Current I Ampere A Area A m2 x Current Density Calculator is a free online tool that.
A cross-sectional area of the conductor m 2. J I A Where I is the current flowing through the conducting material. Current Density With this formula you can calculate the current density the electric current and the area.
The current density formula can be expressed as. Using the current density formula determine the current density of a copper. Current density is defined near any point is defined as the amount of electric current flowing perpendicularly to the unit cross-sectional area near that point.
A is the area of the cross. Current density J 2 x 10-3 20 x 10-3 J 010 Am2 Things to Remember Current is defined as the flow of charged particles. J current density amperesm 2 I current through a conductor in amperes.
The current density can also be. Current Density Charge Area Time -1 M 0 L 0 I 1 T 1 M 0 L 2 T 0 -1 M 0 L 0 T 1 -1 M 0 L -2 T 0 I 1.
