Web24 dec. 2024 · Power is calculated by multiplying voltage and current (P = V x I). If a device is rated at 20 watts and draws 0. 5 amperes of current, then the voltage of the device is 40 volts (V = P ÷ I, so V = 20 ÷ 0. 5 = 40). However, the actual voltage of a device can be affected by other factors, such as the resistance of the device and its environment.
