1. Derive the necessary formula/method to determine the effective value or RMS of a triangular wave. Use either a similar method to the class example of the RMS determination of the sinusoidal wave or any other appropriate method.
2. Explain why the presence of harmonics in three phase power supplies causes degradation of the performance of A.C. machines such as motors and transformers.
