What is an electical current?
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.
What is current how it is measured?
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'.
A complete path for electric current to follow is called a?
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.
What causes a current in an electric circuit?
Voltage causes current to flow in an electric circuit.
A break in the wires of an electric current will the circuit and the current?
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 what?
Electric current is defined as the movement of electrical charges.
Defined as a device that changes sound into electric current?
The telephone does that!
What m-word is defined as a device that changes sounds into electric current?
microphone

What is an elecrical current?
Electric current is the flow of charge from one place to another. Charge is carried by electrons, so current can be defined as the number of electrons per second that pass through a given area.
What is conductivity of milk?
The conductivity of the milk is defined by the substances in solution which can ionize and which therefore conduct an electric current.
In an electric circuit resistance is?
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.
Give atleast 6 to 7 differences between conventional current and electric current?
can't as there is only one: they are in opposite directions. conventional current flow was defined arbitrarily before the discovery of electrons to permit mathematical analysis of circuits. electron current flow was defined after the discovery of electrons.
What can current be defined as?
Current is the generic term to describe the flow of something. This could be electrons in a wire (electric current) - or the movement of water in a river (a water current). It can also be used to denote "now" as in "the current time is 12.00" or "current affairs"
Can you explain electric current?
Current is the flow of electrons in a system usually taught from positive to ground or zero potential. It is defined by the formula current = voltage/resistance Everything has resistance - even wire.

What is a current in a circuit measured in?
ampsAnswerElectric current is measured by means of an ammeter. Electric current is expressed in amperes (symbol: A), which is defined in terms of the magnetic effect of an electric current -i.e. the force between two, parallel, current-carrying conductors.
