Maximum power rating
WebFor example, if your hi-fi amp is rated at 65 watts, then you would need only 65 mW to drive comparable headphones. (Actually you need less than 65 mW since most people don’t listen to their loudspeakers at 1 meter.) And this is exactly what you find in hi-fi receivers—their headphone jacks typically provide only 10-20 mW of output power. WebThe formula for power rating within watts is P = V*I. P = 10 x 0.04 = 400mW or 0.4 Watts. Example-2: When the current flows throughout a 1.8KΩ resistor which is rated at 0.5 Watts then calculate the maximum safe current flowing through the resistor. We know the values of R = 1.8 KΩ and P = 0.5 Watts
