As we know that the electrical energy and electrical power both are the two major terms associated with electrical and electronics systems. The main fundamental difference between electrical energy and electrical power is the electrical energy represents the amount of work done that causes an electric current to flow through a circuit. As the against or electrical power is defined as the rate at which work is done is an electrical circuit. and the rate is specified according to the unit time. Now let us discuss the basic key difference between electrical energy and electrical power to better understand this topic.
Definition of electrical energy:
Electrical energy is defined as the overall work done in an electrical circuit. The energy is specified as the amount of work done to move an object and the electrical circuit. Thus the work done on the electric charge in order to cause movement is known as the electrical energy.
Definition of electrical power:
Electrical power is defined as the rate at which it is done on an electrical system. As we have discussed recently that doing work generates energy. Thus the power can be given as the rate of consumption of electrical energy.
The main key difference between electrical energy and electrical power:
- The SI unit of the electrical energy is joules and electrical power is measured in watts.
- Energy is denoted by E while in P is used to denote electrical power.
- Electrical energy defines the energy granted due to the movement of charge carriers in a conductor while electrical power specifies the rate of consumption of electrical energy by a device.
- The produce of power and time give the value of energy however power is the produce of potential difference existing across 2 ends of a conductor and the current flowing through it.
- The electrical energy is defined as the E = VI.t while in Electrical power is defined as the P = V*I.
- Electrical energy is the energy generated as the result of the potential difference in a circuit which causes current to flow through it while the electrical power is the rate of the amount of electrical energy transferred.
