Answer:
(1.6 × 10¹⁸) /s
Explanation:
Current flowing in a wire is given by
I = (Q/t)
where Q = total charges on the electrons flowing in the wire
t = time
But Q = nq
where n = number of electrons flowing in the wire
q = charge on one electron = 1.602 × 10⁻¹⁹ C
So, I = nq/t
(n/t) = (I/q)
(n/t) = number of electrons per second, for any cross sectional Area.
(n/t) = (I/q)
I = 260 mA = 0.26 A
q = 1.6 × 10⁻¹⁹ C
(n/t) = (0.26/(1.602×10⁻¹⁹)) = (1.62 × 10¹⁸) /s = (1.60 × 10¹⁸) /s
