Concepts Of Current Voltage Power Energy And Their Units
The watt is the si unit of power defining the rate of energy conversion and it is equivalent to one joule per second.
Concepts of current voltage power energy and their units. A voltage source such as battery that forces electric charge to move through the rest of the circuit from one terminal of the voltage source back to the other and an unbroken path through the rest of the circuit along which the charge can move. 1v 1j 1c. This formula can be used to substitute for the voltage or for the current in the power formula and the power output of a battery. Basic concept of current voltage power and energy september 16 2017 basic electrical to understand the electrical concept it is necessary to properly know about current voltage power and energy.
Voltage voltage is independent of the exact path the charge takes from a to b. Power p is the rate of energy transfer it is measured in watts w where one watt is defined as one joule per second hence watts can be expressed in base units as kgm 2 s 3. 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. Volt is the electrical unit of voltage.
The watt can be defined according tot he application. Voltage denoted by v is used. To learn more visit byju s. The unit for power is the watt w which is equal to a joule per second this relation can be found from the formula for power the power used or dissipated by a resistor can be found using the formula v ir.
One watt is the rate at which work is done when a current of one ampere i of current flows through a network which has an electrical potential difference of one volt v. Voltage is the energy e per charge q voltage is measured in volts v which is defined as one joule per coulomb voltage can be defined in base units as kgm 2 s 3 a 1. The units of voltage are volts v. One volt is the energy of 1 joule that is consumed when electric charge of 1 coulomb flows in the circuit.
Electrical definition of the watt. Electric power is usually produced by electric generators but can also be supplied by sources such as electric batteries it is usually supplied to businesses and homes as domestic mains electricity by the electric power industry. Learn about the concepts of work energy and power in a detailed manner along with the units and examples of work power and energy. The charge that moves through this circuit is called an electric current.
