The current through a wire depends on time as i = i 0 + α sin π t, where i 0 = 10 A and α = 
A. Find the charge crossed through a section of the wire in 3 seconds, and average current for that interval.
Text Solution
Verified by ExpertsThe correct answer is:
CHECK THE SOLUTION.
(31 C, 
A)
Sol. i = i o + α sin π t.
= 10 + 
sin π t
q = 
= 10 × 3 + 
× 
× 2 = 31 C
Average current = 
= 
A
