Question

DIRECTION: In the following questions, a statement of assertion (A) is followed by a
statement of reason (R). Mark the correct choice as:
(a) Both assertion (A) and reason (R) are true and reason (R) is the correct explanation of assertion (A).
(b) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation of assertion (A).
(c) Both assertion (A) and reason (R) are true but reason (R) is not the correct explanation
(d) Assertion (A) is false but reason (R) is true.
(e) Both Assertion and Reason are false.

11. Assertion : The connecting wires are made of copper.
Reason : The electrical conductivity of copper is high.
12. Assertion : All electric devices shown in the circuit are ideal. The reading of each of ammeter (A) and voltmeter (V ) is zero.
Reason : An ideal voltmeter draws almost no current due to very large resistance, and hence (V ) and (A ) will read zero.


13. Assertion : The resistivity of conductor increases with the increasing of temperature
Reason : The resistivity is the reciprocal of the conductivity.
