The average value of a.c. voltage is given by V = V _ m ( t ) over time interval t=0 to = is
Options
- Av _ m
- B0
- CV _ m
- D2 ~V _ m
Correct answer
D. 2 ~V _ m
Step-by-step solution
What is the average value of ac voltage V = V ₀ t over the time interval t=0 to t= aligned & V _ av = ₀^ Vdt ₀^ dt = ₀^ V ₀ t dt [ t ]₀^ / & = V ₀ - t ₀^ & =- V ₀ [ - 0] aligned
