The current in the electric hotplate circuit is 1.4 A. What electric charge passes through the cross section of its spiral in 10 minutes.
The current in the circuit I is equal to the number of charges q per unit time t.
I = q / t, whence q = I * t,
t = 10 min = 10 * 60 s = 600 s
q = 1.4 a * 600 s = 840 A * s = 840 Cl.
