9(a) The time dependent power is,
(b) From graph we can see that the average power is half of the final value, hence we can say that the average value is,
Since I0 and V0 are constants, we can take them out of the brackets which calculate the average.
(c) The time averaged power is,
(d) The time averaged power can be written as,
(e) We can write the average power as,
(f) The advantage of mentioning rms values of I and V are that, it allows us to get an idea of how much power is there in the electrical energy passing through the wire. This average power can be used to design more efficient electronic circuits, as for AC signals rms values are more important than peak values.
