Assertion: The division are equaly marked on the scale of `AC` ammeter

1.	Assertion: The division are equaly marked on the scale of `AC` ammeter. Reason: Heat produced is directely proportional to the currentA. If both the assertion and reason are true and reason is a true explantion of the assertion.B. If both the assertion and reason are true but the reason is not true the correct explantion of the assertion.C. If the assertion is true but reason falseD. If both the assertion and reason are false.
Answer» Correct Answer - D An `AC` ammeter is consturcted on the basics of heating effect of the electric current. Since heat produced varies as square of current `(H=I^(2)R)`. Therefore the division marked on the scale of `AC` ammeter are not equally spaced.
