Question

The current flowing through a wire depends on time
as i = a + bt where a = 2 A and b = 5 A/s, then
average current between 1 = 1 s to t = 2 s, is
(1) 7A (2) 9.5 A (3) 5 A (4) Zero​

Answer 1

Answer:

Plot graph of current with respect to time.

Area of graph between 1s and 2s divides by time (which is 2-1= 1s) will give you average current.

Or you can use integration
