Resistor Pulse Power Calculator

Formula

To calculate the Resistor Pulse Power (RPP):

\[ RPP = PW \times RF \times \frac{V^2}{R} \]

Where:

\(RPP\) 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)

What is Resistor Pulse Power?

Resistor Pulse Power (RPP) is the amount of power that a resistor dissipates when subjected to a pulsed voltage. This calculation takes into account the pulse width, repetition frequency, instantaneous voltage, and the rated resistance of the resistor. It is essential for understanding the power handling capabilities of resistors in pulsed circuits.

Example Calculation 1

Let's assume the following values:

Pulse Width (\(PW\)) = 0.001 s
Repetition Frequency (\(RF\)) = 1000 Hz
Instantaneous Voltage (\(V\)) = 10 volts
Rated Resistance (\(R\)) = 50 ohms

Using the formula:

\[ RPP = 0.001 \times 1000 \times \frac{10^2}{50} = 1 \times \frac{100}{50} = 2 \text{ watts} \]

The Resistor Pulse Power (RPP) is 2 watts.

Example Calculation 2

Let's assume the following values:

Pulse Width (\(PW\)) = 0.005 s
Repetition Frequency (\(RF\)) = 500 Hz
Instantaneous Voltage (\(V\)) = 20 volts
Rated Resistance (\(R\)) = 100 ohms

Using the formula:

\[ RPP = 0.005 \times 500 \times \frac{20^2}{100} = 2.5 \times \frac{400}{100} = 10 \text{ watts} \]

The Resistor Pulse Power (RPP) is 10 watts.
