                                                   Subject: Physics
                                     Ch- Electric current and simple circuit
                                             Subtopic: Electric Current


        INSTRUCTIONS:
        For Assertion& Reason question follow the following directions.
               DIRECTION: Each of these questions contains an Assertion followed by Reason. Read them carefully
               and answer the question on the basis of following options. You have to select the one that best describes
               the two statements.
               (a) If both Assertion and Reason are correct and Reason is the correct explanation of Assertion.
               (b) If both Assertion and Reason are correct, but Reason is not the correct explanation of Assertion.
               (c) If Assertion is correct but Reason is incorrect.
               (d) If Assertion is incorrect but Reason is correct.
                (e)If Assertion & Reason both are incorrect


               1        Assertion: A complete circuit is called a closed circuit.                            1
                        Reason: Current flows through a open circuit.
