What charge flows through the galvanometer coil connected to the circuit for 2 minutes if the current is 12 mA?
| August 6, 2021 | education
Initial data: t (time during which the galvanometer was included in the circuit) = 2 min (120 s); I (current in the galvanometer coil) = 12 mA (12 * 10-3 A).
The charge that will pass through the galvanometer coil is determined from the formula for calculating the current strength: I = q / t, whence q = I * t.
Calculation: q = 12 * 10-3 * 120 = 1.44 Cl.
Answer: In 2 minutes, a charge of 1.44 Cl will pass through the galvanometer coil.
