Initial data: U (voltage on a car bulb) = 12 V; A (work done by the charge when passing through the filament of the bulb) = 1200 J.
The value of the electric charge can be expressed from the formula: A = q * U, whence q = A / U.
Let’s calculate: q = 1200/12 = 100 Cl.
Answer: A charge of 100 C passed through the filament of a car bulb.
