Example 12.1 A current of 0.5 A is drawn by a filament of an electric bulb for 10 minutes. Find the amount of electric charge that flows through circuit. Current drawn = I = 0.5 A Time taken = t = 10 minutes = 10 Γ— 60 seconds = 600 seconds We need to find charge flowing (Q) We know that Current = (πΆβ„Žπ‘Žπ‘Ÿπ‘”π‘’ π‘“π‘™π‘œπ‘€π‘–π‘›π‘”)/(π‘‡π‘–π‘šπ‘’ π‘‘π‘Žπ‘˜π‘’π‘›) I = 𝑄/𝑑 I Γ— t = Q Q = I Γ— t Q = 0.5 Γ— 600 Q = 5/10 Γ— 600 Q = 5 Γ— 60 Q = 300 C Charge flowing is 300 C
