What is the formula that relates watts, volts, and amps?

Explanation:
Power in electrical circuits is determined by how much electrical energy is used over time. The relationship among watts, volts, and amps is given by Watts = Volts × Amps. This means the power (in watts) equals the voltage (in volts) multiplied by the current (in amps). In AV and electronics contexts, this helps you size power supplies and predict how much power a device will draw. If you know two of the quantities, you can find the third (for example, I = P/V or P = V × I). The other options—Chrominance, RGB color space, and luminance—are color-related terms and don’t describe electrical power.
