Question

A current of 0.5 is drawn by a filament of electric bulb for 10 mins. Find the amount of electic charge that flow through the circuit

Answer 1

as we knoe the formula
current = charge /time
so charge =current ×time
but take time in seconds
so time =10min=10×60sec=600sec
charge=0.5×600=300 coulomb

$\sf{I = 0.5 A \: \:, t = 10 min}$

$\sf\underline{\underline{\pink{To \: find ➣}}}$

$\sf{Q = ?}$

───────────────────────

$\sf\underline{\underline{\pink{Solution➣}}}$

$\sf{1 \: min = 60 \: sec}$

$\sf{∴ 10 \: min = 600 \: sec}$

$\sf{∴ I = \frac{Q}{t} }$

$\sf{↠0.5 = \frac{Q}{600} }$

$\sf{↠0.5 \times 600 = Q}$

$\sf{\underline{\underline{\bold{∴ Q = 300 C}}}}$
