(a) Determine the equation for the waveform of Figure 1, given f = 60 Hz. (b) Compute current at t = 4 m
Answer :-
question figure is not given in question but i got - figure is given below
Note- I am making graph by hand , so that i can make more clear and it cannot be possible by online graph
Given the waveform of current.
Given frequency f=60 Hz
Since from fundamental we know
now shift the waveform from right
Here Maximum value of current Im=2
so and w=2 ; f=60 Hz ; w=377
so
and value of current at t=4 m
