If the current in a circuit is 2A, calculate:
a) The charge that crosses a point in the circuit in 0.6s.
b) The number of electrons crossing the point per second. Take e=1.6*10-19C.

a) The charge that crosses a point in the circuit in 0.6s.
I=Q/t
Q=2*0.6 =1.2C
b) The number of electrons crossing the point per second. Take e=1.6*10-19C.
I=Q/t = ne/t
1.2/0.6 = (n*1.6*10-19)/0.6
n= 1.2/ (1.6*10-19) = 7.5*1018 electrons
