The formula for calculating wattage is: W (joules per second) = V (joules per coulomb) x A (coulombs per second) where W is watts, V is volts, and A is amperes of current.

What is SI unit of power?
The SI unit of power is the watt (W), in honor of Scottish inventor James Watt (1736 – 1819). … One watt equals one joule per second (W = J / s).
What does Joule’s law state?
noun Physics. the principle that the rate of production of heat by a constant direct current is directly proportional to the resistance of the circuit and to the square of the current. the principle that the internal energy of a given mass of an ideal gas is solely a function of its temperature.
How do I calculate power?
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .

Does more watts mean more bass?
More bass does not necessarily mean better bass. The power is determined by the wattage of the subwoofer in question, where a higher wattage demonstrates a more powerful subwoofer. … Wattage is a rough indicator of how powerful a subwoofer can be, not how it should be played!
Does higher wattage mean stronger motor?
The wattage rating is usually (read the manufacturer’s specs very carefully) the measure of how much power the motor can draw. It doesn’t tell you anything more than that. Wattage does not tell you whether the motor is efficient at converting the input electrical energy into output mechanical energy.
Can a PSU have too much wattage?
No, an overkill power supply will not damage your PC. It’s not forcing excess power into your system. Your system takes what it needs. PSU’s are generally most efficient at half load, so if your machine uses 350 watts max, getting a 650 or 750 watt psu would save energy, and a 1000 watt would waste a little.
