RMS and average voltage

Question

Answer 1

(1)

 and  sec.

Observe the graph:

Two points in the interval  are (0, 0) and (2, 10).

Slope = . 

Point-slope form of the equation is .

Slope = 5 and the point is (0, 0).

Find RMS voltage by using the formula: .

Substitute  and  in above expression.

 Volts.

Answer 2

(2)

Find the average voltage.

From the results of (1)-bit, the voltage is  in  .

Averagre voltage: .

Substitute  and  in above expression.

 Volts.
