Directions : In the following questions, A statement of Assertion (A)...
An ac ammeter is constructed on the basics of heating effect of the electric current. Since heat produced varies as square of current (H=I2R). Therefore the division marked on the scale of ac ammeter are not equally spaced.

Directions : In the following questions, A statement of Assertion (A)...
Assertion: The divisions are equally marked on the scale of an AC ammeter.
Reason: Heat produced is directly proportional to the current.
Explanation:
Assertion: The divisions are equally marked on the scale of an AC ammeter.
Reason: Heat produced is directly proportional to the current.
The given assertion and reason are both incorrect. The correct answer is option 'D'.
Explanation:
AC Ammeter Scale:
An AC ammeter is an instrument used to measure the alternating current flowing through a circuit. The scale of an AC ammeter is divided into equal divisions to represent different values of current.
Heat produced and Current:
The reason given in the question states that heat produced is directly proportional to the current. However, this is not entirely true. While it is true that heat is produced when current flows through a conductor, the relationship between heat and current is not solely proportional.
The amount of heat produced in a conductor depends on various factors including the resistance of the conductor, the time for which the current flows, and the energy dissipated in the form of heat.
Ohm's Law:
According to Ohm's Law, the current flowing through a conductor is directly proportional to the voltage across it and inversely proportional to the resistance of the conductor. The equation representing Ohm's Law is:
I = V/R
Where I is the current, V is the voltage, and R is the resistance.
Therefore, it can be concluded that the heat produced in a conductor is directly related to the current, voltage, and resistance. It is not solely dependent on the current flowing through the conductor.
Conclusion:
In conclusion, the given assertion and reason are both incorrect. The divisions on the scale of an AC ammeter are not marked equally because of the relationship between heat produced and current is not solely proportional.
Reason: Heat produced is directly proportional to the current.
Explanation:
