Find the average value of current shown graphically from t=0 to t=2 ~s .

Options

  1. A3 A
  2. B5 A
  3. C10 A
  4. D4 A

Correct answer

B. 5 A

Step-by-step solution

From i-t graph, area from t=0 to t=2 ~s , we get aligned & = 1 2 1 10+ 1 2 (2-1) 10 & =5+5=10 ~A Area current, i_ av & = Area (i-t) graph time interval = 10 2 =5 ~A aligned
