Electric current is a measure of the amount of electrical charge transferred per unit time. It represents the flow of electrons through a conductive material. THE SI UNIT OF ELECTRIC CURRENT IS THE AMPERE. AND FORMULA IS 1.V: voltage. 2.I: current.
What is electric current give its formula?
Electric current is defined the flow of electric charge in a conductor. The SI unit of electric current is Ampere. The formula of electric current is: I = charge/time. (0)
What is electricity write its unit?
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. Electric power is usually produced by electric generators, but can also be supplied by sources such as electric batteries.
What is current and its unit?
Current is a flow of electrical charge carriers, usually electrons or electron-deficient atoms. … The standard unit is the ampere, symbolized by A. One ampere of current represents one coulomb of electrical charge (6.24 x 1018 charge carriers) moving past a specific point in one second.
What are types of current?
There are two kinds of current electricity: direct current (DC) and alternating current (AC). With direct current, electrons move in one direction. Batteries produce direct current. In alternating current, electrons flow in both directions.
What is Ohm’s law state?
Ohm’s law states that the current through a conductor is proportional to the voltage across the conductor. … V=IR where V is the voltage across the conductor and I is the current flowing through it.
How do I calculate power?
Power is equal to work divided by time. In this example, P = 9000 J /60 s = 150 W .
What is unit charge?
The unit of charge is the coulomb, and it is defined as the amount of electric charge (q) transported by a constant electric current of one ampere in one second. … In electrostatics, we use the charge of an electron or a proton (Both have the same magnitude of charge) as the unit charge.
What is the current unit?
Unit of electric current: ampere (A)
The ampere, symbol A, is the SI unit of electric current. It is defined by taking the fixed numerical value of the elementary charge e to be 1.602 176 634 ×10−19 when expressed in the unit C, which is equal to A s, where the second is defined in terms of ∆νCs.
