Enter the total field charge (C) and the permittivity (F/m) into the Outward Flux Calculator. The calculator will evaluate the Outward Flux. 

Outward Flux Formula

The following two example problems outline the steps and information needed to calculate the Outward Flux.

OF = C / P


  • OF is the Outward Flux (N-m^2/C)
  • C is the total field charge (C) 
  • P is the permittivity (F/m) 

To calculate the outward flux, divide the total field charge by the permittivity.

How to Calculate Outward Flux?

The following steps outline how to calculate the Outward Flux.

  1. First, determine the total field charge (C). 
  2. Next, determine the permittivity (F/m). 
  3. Next, gather the formula from above = OF = C / P.
  4. Finally, calculate the Outward Flux.
  5. After inserting the variables and calculating the result, check your answer with the calculator above.

Example Problem : 

Use the following variables as an example problem to test your knowledge.

total field charge (C) = 300

permittivity (F/m) = 10

OF = C / P = ?
