Sketching three-phase generator output at 300rpm with 30V amplitude

[boyblair]

Homework Statement

In a particular application, the generator output is converted to DC and used to power an immersion element for water heating.

1). Sketch the shape of the output voltage at a rotation speed of 300 rpm assuming the amplitude on each phase is 30V?

The Attempt at a Solution

Really don't know where to start with this one, any advice?

A generator consists of a rotating coil in a magnetic field. The p.d. generated by the generator is thus governed by the laws of electromagnetic induction. You should go and read up, otherwise you will not really appreciate the context of the question.
