What is the basic unit of power in a DC circuit?

Explanation:
Power in a DC circuit is the rate at which electrical energy is transferred or used. The basic unit for that rate is the watt. In electrical terms, power is the product of voltage and current, P = V × I, so the energy delivered per second is measured in watts. One watt equals one volt times one ampere. That links the units: joule is a unit of energy, while volt is potential difference and ampere is current. For example, a device with 5 volts across it drawing 2 amperes uses 10 watts of power.
