To calculate the Headphone Power (HP):
\[ HP = \frac{V^2}{R} \]
Where:
Headphone power refers to the amount of electrical energy that a pair of headphones requires to function and produce sound. It is typically measured in milliwatts (mW) and is directly related to the volume and quality of sound that the headphones can produce. The power is supplied by the device the headphones are connected to, such as a smartphone, computer, or audio amplifier. The higher the headphone power, the louder and clearer the sound can be, but too much power can potentially damage the headphones.
Let's assume the following values:
Using the formula:
\[ HP = \frac{2^2}{32} = \frac{4}{32} = 0.125 \text{ watts} \]
The headphone power is 0.125 watts (or 125 milliwatts).
