What is the relationship between the coil's position and the a.c. output in a simple generator?
The a.c. output is constant.
The a.c. output varies with the coil's position.
The a.c. output increases linearly.
The a.c. output is zero.
คำอธิบาย
The output voltage varies depending on the coil's position relative to the magnetic field.
