Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second. … It is usually supplied to businesses and homes (as domestic mains electricity) by the electric power industry through an electric power grid.
What is electric power class 10th?
Rate at which electric energy is dissipated or consumed in a circuit is called Electric Power. P = VI = I2R = V2/R. SI unit of Power is Watt (W). 1 Watt power is consumed when 1 Ampere of current flows through a device at a potential difference of 1 Volt.
What can electricity power?
Electric energy is unrivaled for many uses, as for lighting, computer operation, motive power, and entertainment applications. For other uses it is competitive, as for many industrial heating applications, cooking, space heating, and railway traction.
What is electrical power and types?
Electric power is classified into two types of electric power and they are: DC power: It is defined as the product of voltage and current and is produced by the generator, battery, and fuel cell. … AC power: There are three types of AC power and they are: Apparent power: It is the ideal power and is represented by S.
What is electric power and electric energy Class 12?
Electric power: It is the rate at which an electric appliance converts electric energy into other forms of energy. … Elecric energy: It is the total workdone in maintaining an electric current in an electric circuit for a given time.
What is volt class 10 CBSE?
One volt is defined as the electric potential between two points of a conducting wire when an electric current of one ampere dissipates one watt of power between those points. …
What is electric power in Brainly?
Electric power is the rate, per unit time, at which electrical energy is transferred by an electric circuit. The SI unit of power is the watt, one joule per second.
What is electric power and energy?
Electric power is the rate at which a device changes electric current to another form of energy. The SI unit of power is the watt. Electric power can be calculated as current times voltage. Electrical energy use equals the power of the appliance multiplied by the amount of time the appliance is used.
Who made electricity?
The electric power is given by P = VI. Where V is the potential difference, I is the electric current and P is the electric power.
What called power?
In physics, power is the amount of energy transferred or converted per unit time. In the International System of Units, the unit of power is the watt, equal to one joule per second. In older works, power is sometimes called activity.
What is electricity short answer?
Electricity is the flow of electrical power or charge. It is a secondary energy source which means that we get it from the conversion of other sources of energy, like coal, natural gas, oil, nuclear power and other natural sources, which are called primary sources.
