A 10-A current flows for two minutes. (a) How much charge has passed through this circuit?...

Question

Question

Answer 1

Answer #1

1.

i = current flown = 10 A

t = time of flow = 2 min = 2 x 60 sec = 120 sec

Q = charge

using the formula

Q = it

Q = 10 (120) = 1200 C

b)

n = number of electrons passed

e = charge on electron = 1.6 x 10^-19 C

charge is given as

Q = ne

1200 = n (1.6 x 10^-19)

n = 7.5 x 10²¹
