Electric power is the rate at which work is done or energy is transformed into an electrical circuit. Electric power is measured in watts. Learn its definition, formula, unit along with solved examples at BYJU'S.
So according to the definition, the electrical power is the rate of flow of electrical energy or the work done on electrical charges in an electrical circuit. The electrical energy is the energy stored in charge Q under the influence of voltage V (potential difference).
Electric power is the rate of transfer of electrical energy within a circuit. Its SI unit is the watt, the general unit of power, defined as one joule per second.
electric power, energy generated through the conversion of other forms of energy, such as mechanical, thermal, or chemical energy. Electric energy is unrivaled for many uses, as for lighting, computer operation, motive power, and entertainment applications.
Power is the rate at which energy of any type is transferred; electric power is the rate at which electric energy is transferred in a circuit. In this section, we’ll learn not only what this means, but also what factors determine electric power.
Electric power is the rate at which electrical energy is transferred. The formula is Power = Current × Voltage: Power (P) is measured in Watts (W), Current (I) is measured in Amps (A), and Voltage (V) is measured in Volts (V). It takes both Current and Voltage to create Power!
An electric circuit is capable of transferring power. Current is the rate of flow of charge, and voltage measures the energy transferred per unit of charge. We can insert these definitions into the equation for power:
Electric power from the definition of power. Multiply by one and commute the variables in the denominator. Look at what this gives us. This is the original definition of the watt as the unit of power. The other unit I would suggest adding to the list is that of power.
