Electric current is simply the flow of free electrons in a conductor. It is usually defined as the rate of charge flow, because the free electrons represent an electric charge.
An electric current (symbol: I) is a very slow drift of charge carriers (electrons, in metallic conductors), and is measured in amperes (symbol: A). An ampere is defined in terms of the 'magnetic effect' of an electric current, that is the force of attraction or repulsion between two, parallel, conductors due to the interaction of their magnetic fields. An instrument used to measure electric current is called an 'ammeter'.
An Electric PathA complete path for an electric current to follow is called a closed circuit. Ampere is the SI unit for measuring an electric current.
Voltage causes current to flow in an electric circuit.
A break in the wires of an electric current will break or cut the circuit and stop the current from flowing.
Electric current is defined as the movement of electrical charges.
The telephone does that!
A microphone is the device that changes sounds into electric current.
The basic unit of electric current is the ampere (A). It is defined as the flow of one coulomb of electric charge per second.
Electric current is simply the flow of free electrons in a conductor. It is usually defined as the rate of charge flow, because the free electrons represent an electric charge.
The base unit of electric current flow is the Ampere, symbolized as A. It is defined as the flow of one Coulomb of charge per second.
One coulomb per second is defined as an ampere (A), which is the unit of electric current. It represents the flow of one coulomb of electric charge per second in a circuit.
The energy carried by an electric current depends on the voltage of the source and the amount of charge flowing through the circuit. It is defined as the product of voltage, current, and time.
The conductivity of the milk is defined by the substances in solution which can ionize and which therefore conduct an electric current.
Resistance is the opposition to the flow of electric current through a conductor. It is defined as the ratio of the potential difference (volts) between the ends of the conductor to the magnitude of the current (amps) through the conductor.
The movement of electrical charge on a material is called electric current. It is defined as the flow of electric charge through a medium, such as a wire, in response to an electric field.
The SI unit for electrical current is the ampere, symbol A. It is defined as the flow of electric charge per unit of time, equivalent to one coulomb per second.
