MCQ
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 $\ce{(a), (b), (c)}$ and (d) as given below :
Assertion : The wires supplying current to an electric heater are not heated appreciably.
Reason : Resistance of connecting wires is very small and $\text{H}\propto\text{R}.$
  • ✓
    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.
✓

Answer

Correct option: A.
Both $A$ and $R$ are true, and $R$ is correct explanation of the assertion.
Resistance of the connecting wires is much smaller than the electric appliances to which current is supplied by the wires.
