Enter the number of carrier charges and the total volume into the Calculator. The calculator will evaluate the Carrier Density. 

Carrier Density Formula

n = N/V


  • n is the Carrier Density ()
  • N is the number of carrier charges
  • V is the total volume

To calculate Carrier Density, divide the number of carrier charges by the total volume.

How to Calculate Carrier Density?

The following steps outline how to calculate the Carrier Density.

  1. First, determine the number of carrier charges. 
  2. Next, determine the total volume. 
  3. Next, gather the formula from above = n = N/V.
  4. Finally, calculate the Carrier Density.
  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.

number of carrier charges = 5.6

total volume = 80
