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.
Another Answer
There is no relationship between current and the cross-sectional area of a conductor.
The thicker the conductor, the less the current that will flow through.
Conductor-one which conducts(allow current)electric city in all condition. Semiconductor-One which behaves like conductor as well as insulator depending on condition. Insulator-one which donot conduct(allow current)electric city in all condition
The term, 'overcurrent', describes either an 'overload current' or a 'short-circuit current'.An 'overload current' is a current that is higher than a circuit's 'rated current'. For example, if you have too many loads plugged into the same circuit, then the resulting current is an 'overload current'.A 'short-circuit current' is a large current resulting when a line ('hot') conductor accidentally makes contact with either a neutral conductor or an earth (ground) conductor.
pogi current flow in the armature conductor
Current specifically refers to the movement electrons through an electric conductor. Electricity is a more general term.
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).
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
-- 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.
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,...
The thicker the conductor, the less the current that will flow through.
Conductor will carry current/insulator won't.
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.
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.
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.
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 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.
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'.
