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 relation between current and thikness of conductor?
The thicker the conductor, the less the current that will flow through.
What is the difference between over current and overload 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.
Differentiate in between conductor and semiconductor and insulators using band diagram?
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
What kind of current flows in the armature conductor of a dc generator?
pogi current flow in the armature conductor
What is the difference between the current and electricity?
Current specifically refers to the movement electrons through an electric conductor. Electricity is a more general term.
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.
What is relationship exists between the magnetic force and current through conductor?
The magnetic force experienced by a current-carrying conductor is directly proportional to the magnitude of the current flowing through it. This relationship is described by the right-hand rule for magnetic fields, where the direction of the force on the conductor can be determined by pointing the thumb of your right hand in the direction of the current and the fingers in the direction of the magnetic field.
What is the relationship between voltage and current called?
The relationship between voltage (V), current (I) and resistance (R) is known as Ohm's Law. It states that the current flowing through a conductor is directly proportional to the voltage applied across it, and inversely proportional to the resistance of the conductor. The equation is expressed as V = I * R.
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 link between eleltricity and magnatisim?
The link between electricity and magnetism is described by electromagnetism, a fundamental force of nature. When an electric current flows through a conductor, it generates a magnetic field around the conductor. Similarly, a changing magnetic field can induce an electric current in a nearby conductor, demonstrating the close relationship between electricity and magnetism.
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 the principles of electomagnet?
The principles of electromagnetism involve the relationship between electric currents and magnetic fields. When an electric current flows through a conductor, it creates a magnetic field around the conductor. The strength of the magnetic field is directly proportional to the current flowing through the conductor and inversely proportional to the distance from the conductor. This phenomenon forms the basis for electromagnets and various electrical devices.
What does a conductor do in a magnetic field when current is suddenly passed through it?
When current is suddenly passed through a conductor in a magnetic field, it experiences a force due to the interaction between the magnetic field and the current. This force causes the conductor to move, resulting in electromagnetic induction and the generation of an electric current in the conductor.
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.
