A current of 0.5 A is drawn by a filament of a clectric bulb for 20 minutes. The amount electric charge that flows through the circuit is

To calculate the amount of electric charge (Q) flowing through a circuit, the standard formula used is Q = I × t, where 'I' represents the electric current in amperes and 't' represents the time in seconds . In this problem, the current (I) is given as 0.5 A and the time (t) is 20 minutes. Since the SI unit for time in this calculation must be seconds, 20 minutes is converted by multiplying by 60, resulting in 1200 seconds . Substituting these values into the formula gives Q = 0.5 A × 1200 s, which equals 600 Coulombs (C) . This fundamental relationship defines current as the rate of flow of charge, where one Coulomb is the charge transported by a constant current of one ampere in one second. Therefore, the total charge that flows through the filament is 600 C.
