As per the question we are asked about the method to determine the phase angle of current relative to a voltage.
00:19
So, to determine the phase angle of current relative to voltage, we have two different methods.
00:28
These two different methods are the timing method, the timing method.
00:35
The second method is the waveform equation method, the waveform equation method.
00:44
To understand these two methods, we have number one that is the timing method, the timing method.
00:53
Now, according to this timing method, let us take this as a graph for time t.
01:00
This is the wave showing the voltage that is this is for voltage.
01:08
This wave, the dotted wave shows the current.
01:14
This looks something like this.
01:17
This wave shows, the dotted one shows current.
01:21
This difference between the two waves will be delta t.
01:27
So, what is this delta t? this is difference in time interval, difference in time.
01:33
What happens is that an oscillator, an oscilloscope or oscillator track the current and voltage waveform, current and voltage waveform which are shown in the diagram.
01:55
Now, what happens is that current i and voltage v with frequency, frequency omega...
