I = 1.5 A.
Q = 300 Cl.
t -?
According to the definition, the current I is a scalar physical quantity equal to the ratio of the charge Q, which passes through the cross section of the conductor, to the time t, during which this charge has passed.
I = Q / t.
Let us express the transit time of the charge: t = Q / I.
t = 300 C / 1.5 A = 200 s.
Answer: the charge passes in t = 200 s.
