Question
Two sinusoidal voltages of the same frequency are shown in the diagram. What is the frequency, and the phase relationship between the voltages
Frequency in Hz Phase lead of N over M in radians</span
- 0.4
- 2.5
- 2.5
- 2.5
The correct answer is: 2.5
From the graph shown below. It is clear that phase lead of N over M is 
. Since time period (i.e. taken to complete one cycle) = 0.4 sec.
Hence frequency
