Explanation:

Electrodynamometer:
An electrodynamometer is a type of instrument used to measure electric current. It consists of two coils - a fixed coil and a moving coil.

Principle:
The deflection of the pointer in an electrodynamometer ammeter is proportional to the mean square of the currents in the fixed coil and moving coil.

Mean Square of Currents:
- The mean square of currents in the fixed coil and moving coil is calculated by taking the square of each current, then finding the mean or average value of these squared currents.

Proportional Deflection:
- The deflection of the pointer is directly proportional to the mean square of the currents in the fixed coil and moving coil.
- This means that as the mean square of the currents increases, the deflection of the pointer on the ammeter also increases.

Correct Answer:
Therefore, the correct answer is option 'D' - mean square of currents in the fixed coil and moving coil. This relationship between the deflection of the pointer and the mean square of currents allows for accurate measurement of electric current using an electrodynamometer ammeter.
