Define electric current.
For two statements are given-one labelled Assertion (A) and the other labelled Reason (R). Select the correct answer to these questions from the codes (a), (b), (c) and (d) as given below:
(a) Both A and R are true, and R is correct explanation of the assertion.
(b) Both A and R are true, but R is not the correct explanation of the assertion.
(c) A is true, but R is false.
(d) A is false, but R is true.
Assertion: Good conductors of heat are also good conductors of electricity and vice versa.
Reason: Mainly electrons are responsible for conduction.
What is meant by potential difference between two points?
List two differences between a voltmeter and ammeter.

Assertion: A current carrying wire should be charged.
Reason: The current in a wire is due to flow of free electrons in a definite direction.
