Saw toothed waveform means that its voltage:
Correct answer: C. Increases linearly with time and then drops to zero
- A. Decreases linearly with time
- B. Increases linearly with time
- C. Increases linearly with time and then drops to zero
- D. None of these
Explanation
In a saw-tooth waveform, the voltage increases linearly with time, but instead of dropping to zero, it rapidly drops back to its starting voltage after reaching its peak value.

About Electromagnetism
Magnetic flux density and magnetic flux describe the strength of a magnetic field and the field passing through a surface. A charged particle moving through a magnetic field experiences a force perpendicular to its velocity and may follow circular or helical motion, depending on the angle between velocity and field.
