The property of a conductor due to which it opposes the flow of current is known as:
Resistance.
Conductance.
Convection.
None of these.
The property of a conductor due to which it opposes the current flowing through it is known as the resistance of the conductor.
What is the difference between resistance and resistivity in terms of definition ?
i.e. resistance is defined as the property of conductor due to which it opposes the flow of electric current through it.
Then how can we define resistivity in a similar way ?
due to increase in temperature the resistance of a conductor increases due to increased number of conduction electrons but if there will be more charges there will be more current and current is inversely proportional to resistance then how it increases the resistance of the conductor?
