How much electricity flows through the coil connected to the circuit for 1.5 minutes if the current in the circuit is 18 μA?

Initial data: t (duration of the coil in the circuit) = 1.5 min; I (current in the circuit) = 18 μA.

SI system: t = 1.5 min = 1.5 * 60 = 90 s; I = 18 μA = 18 * 10 ^ -6 A.

The amount of electricity that will pass through the coil is determined by the formula: q = I * t.

Let’s make a calculation: q = 18 * 10 ^ -6 * 90 = 1620 * 10 ^ -6 C = 1.62 mC.

Answer: 1.62 mC of electricity will pass through the coil in 1.5 minutes.
