True or false 6. Sine wave leading the cosine wave by 90°. 7. If the voltage across a coil is sinusoidal in nature, the resulting current will also have sinusoidal characteristics. 8. As the angular velocity increases the period for a waveform increases too. 9. An angle of 0.87 equivalent to 45º. 10. You can examine the leading and lagging properties for waveforms if they have the same frequency only.
