1. The problem statement, all variables and given/known data What will the pointer of electrodynamic ammeter show (its natural frequency of oscillation is 5 Hz), if its input is energized by current: a) i (t) = 1.5 + 4 sin (3146 t) b) i (t) = 1.5 + 4 sin (2 t) Ammeter has a range of 6 A and the scale has 100 divisions. 2. Relevant equations 3. The attempt at a solution My solution is 25 but I don't understand the difference between a) (where the frequency is 500 Hz) and b) (0.318 Hz).
