Best Answer

Specific resistivity is directly proportional to area of cross section of the conductor and specific conductivity is the inverse of specific resistivity. So we can say , Specific conductivity is directly proportional to area of cross section of the conductor.

consider a circuit with a constant voltage supply i.e. voltage,V is constant.now from Ohm's law we have V=IR,where I is the current and R is the resistance.and the resistance of the conductor is inversely is proportional to the cross sectional area,A.from the relation V=IR,where V is constant,I is inversely proportional to R and since R is inversely proportional to A, I is directly proportional to A.

What is the relationship between the deflection of the wire and the current?

the relationship between the deflection of the wire and the ccurrent is when the voltage is 12volt the current become higher.Another AnswerPresumably you are referring to the force on a conductor placed in a magnetic field? In which case, it is equal to the Flux Density of the field (in teslas), the length of the conductor within the field (in metres), and the value of the current passing through the conductor (in amperes).


What is the relationship between voltage and MA?

The "current" through any conductor is voltage across the conductor/conductor's resistance .The current is measured in "Amperes" (amps)."MA" stands for "Milliamps". There are 1,000 of those in one whole ampere.So, the current through a conductor is1,000 times the voltage across the conductor/conductor's resistance . . . in MA


What is the relationship between magnetic fields and electricity?

-- A current flowing through a conductor creates a magnetic field around the conductor. -- Moving a conductor through a constant magnetic field creates a current in the conductor. -- If there's a conductor sitting motionless in a magnetic field, a current flows in the conductor whenever the strength or direction of the magnetic field changes.


Is diode ohmic or non-ohmic conductor?

Diode is a non-ohmic conductor since in diodes current-voltage relation ship does't obey Ohm's law....the relationship between current and voltage is nonlinear here,...


What is the relation between current and thikness of conductor?

The thicker the conductor, the less the current that will flow through.

What did Andre ampere discovered?

Ampere disconvered the relationship between the magnitude of an electric current and the force acting on a current-carrying conductor within a magnetic field. Thus, the unit of current, the ampere, was named in his honour.


What relationships did ohm discover between the three factors?

Ohm detected the following one V = R * I Here V is the potential difference across a conductor. R- resistance of the conductor and I is the current that flow through the conductor.


Can an overhead conductor carry more current on a cold day as compared to a hot day?

The only limit on how much current the conductor can carry, regardless ofthe weather, is the amount of current that causes the conductor to melt.The current in such a conductor depends on the voltage between its ends,and on the resistance of the conductor. The resistance of the conductor issomewhat less when it's cold, so a given voltage would result in more 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.


What happens to the electrons in a conductor when there is a potential difference between the conductor's ends?

The free electrons in a conductor will, when a difference of potential (voltage) is applied at its ends, participate in electron current flow (or just current, if you prefer). The voltage applied to the conductor will drive current through the conductor, and the free electrons will support current flow. These electrons will actually move through the conductor. As electrons are driven into one end of the conductor, the free electrons "shift over" and electrons stream out the other end of the conductor. This is the essence of current flow in conductors.


What is the relationship between current and current density?

Current (I) is measured in amperes, which is an SI Base Unit, defined in terms of the force (expressed in newtons) between two, parallel, current-carrying conductors.Current is the rate at which electric charge (Q) flows. Electric charge is measured in coulombs, which is an SI Derived Unit, defined in terms of current and time (t) the ampere and the second. That is: Q = I t.So a 'coulomb' is a special name given to an 'ampere second'.
