Enter the pulse width (s), the repetition frequency (Hz), the rate resistance (ohms) and the instantaneous voltage (volts) into the Resistor Pulse Power Calculator. The calculator will evaluate the Resistor Pulse Power. 

Resistor Pulse Power Formula

The following formula is used to calculate the Resistor Pulse Power. 

RPP = PW * RF * V^2/R


  • RPP is the Resistor Pulse Power (watts)
  • PW is the pulse width (s) 
  • RF is the repetition frequency (Hz) 
  • V is the instantaneous voltage (volts) 
  • R is the rated resistance (ohms)

To calculate the resistor pulse power, multiply the pulse width by the repetition frequency, then again by the voltage squared, and finally divide by the rated resistance.

How to Calculate Resistor Pulse Power?

The following steps outline how to calculate the Resistor Pulse Power.

  1. First, determine the pulse width (s).
  2. Next, determine the repetition frequency (Hz). 
  3. Next, determine the instantaneous voltage (volts). 
  4. Next, determine the rated resistance (ohms).
  5. Next, gather the formula from above = RPP = PW * RF * V^2/R.
  6. Finally, calculate the Resistor Pulse Power.
  7. 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.

pulse width (s) = 5

repetition frequency (hz) = 3

instantaneous voltage (volts) = 10

resistance (ohms) = 2

RPP = PW * RF * V^2/R =  ?
