Step 1 :  

Read the formula and observe the given quantities. Use the formula


Current density = Current / Area .


Unit is A / m2



Step 2 :  

State the equation you plan to use and plug in the values.

  1. Find the current density if the area of metal box is 2.3 m2 and current is 67 ampere is flowing through it.


    Step 1 :  

    The given:


    Current = 67 A,


    Area = 2.3 m2,


    Current density = ?



    Step 2 :  

    Plug in the values in the formula, as we know that


    Formula:


    Current density = Current / Area .


    Current density = 67 / 2.3



    Answer  :  

    Current density = 29.130 A / m2



  2. The 145 amper of current flows in the battery at the area of 4.6 m2. Calculate the current density for the battery.


    Step 1 :  

    The given:


    Current = 145 A.


    Area = 4.6 m2.


    Current density = ?



    Step 2 :  

    Plug in the values in the formula as we know that


    Formula:


    Current density = Current / Area .


    Current density = 145 / 4.6



    Answer  :  

    Current density = 31.522 A / m2
