What is the rotational speed of the coil in alternating current and what is the relationship between it and angular velocity
A cycle T of alternating current is a positive half cycle and a negative half cycle
A rectangular line passes through a magnetic field and rotates 360 degrees for a period
The reciprocal of the number of complete cycles t in one minute is frequency f, in Hz
f=1/T
Speed can only determine the period, not the frequency
