The current strength of the electric lamp is 4 A. What charge flows along its spiral in 10 minutes?

The current strength is equal to the ratio of the electric charge q (C) passed through the conductor to the transit time t (s)
I = q / t,
From this formula we find the electric charge
q = I * t.
It follows from the problem that the current strength is I = 4A, the time of passage of the electric charge is t = 10 minutes, but in the SI system the unit of measurement is second (s), we convert minutes into seconds t = 10 * 60 = 600c. We substitute the data into the formula and calculate the electric charge
q = 4A * 600s = 2400Cl. (pendant)
