Question

001 10.0 points How long does it take for 7.0 C of charge to pass through a cross-sectional area of a copper wire if I = 5.9 A? Answer in units of s.
002 (part 1 of 3) 10.0 points Note that parts 2 3 are extra credit! A total charge of 6.5 mC passes through a cross-sectional area of a nichrome wire in 2.8 s. What is the current in the wire? The fundamental charge is 1.602 × 1019 C. Answer in units of A.
003 (part 2 of 3) 10.0 points How many electrons pass through the crosssectional area in 24.0 s?
004 (part 3 of 3) 10.0 points If the number of charges that pass through the cross-sectional area during the given time interval doubles, what is the resulting current? Answer in units of A.

I need help with number 4

Explanation / Answer

When number of charges are doubled, Q= 13 mC in 2.8 sec

I = Q/t = 13/2.8 = 4.64 mA (ans)
