How much electricity flows through the galvanometer coil connected to the circuit for 2 minutes

How much electricity flows through the galvanometer coil connected to the circuit for 2 minutes, if the current in the circuit is 12mA.

Given:

t = 2 minutes – the time during which the galvanometer coil was included in the electrical circuit;

I = 12 mA – current in the electrical circuit.

It is required to determine q (Coulomb) – how much electricity passed through the coil during the time interval t.

Let’s convert time units from minutes to seconds:

t = 2 minutes = 2 * 60 = 120 seconds.

Let’s convert units of measurement of current strength from milliamperes to amperes:

I = 12 mA = 12 * 10-3 = 12/1000 = 0.012 Ampere.

Then the amount of electricity will be equal to:

q = I * t = 0.012 * 120 = 1.44 Pendant.

Answer: An amount of electricity equal to 1.44 Coulomb passed through the galvanometer coil.
