SUMMARY
The discussion focuses on calculating the deflection of an electrodynamic ammeter with a 6 A range and 100 divisions when energized by two different current inputs: i(t) = 1.5 + 4 sin(3146t) and i(t) = 1.5 + 4 sin(2t). The natural frequency of oscillation for the ammeter is 5 Hz. The calculated deflection for the first input is 25 divisions, but the user seeks clarification on the impact of the differing frequencies of the inputs, specifically 500 Hz for the first and 0.318 Hz for the second.
