The property of an electrical component to resist the flow of electric current is termed as electrical resistance.
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 ?
Write an expression for the electrical power spent in flow of current through a conductor in terms of (a) resistance and potential difference (b) current and resistance.
