Answer 1

$\red{\bigstar}\underline{\underline{\textsf{\textbf{ Given :- }}}}$

• A current of 0.2 Ampere is drawn by a filament of an electrical bulb for 5 minutes .

$\red{\bigstar}\underline{\underline{\textsf{\textbf{ To Find :- }}}}$

• The electrical charge passing through the filament .

$\red{\bigstar}\underline{\underline{\textsf{\textbf{ Solution :- }}}}$

Given that a current of 0.2 ampere is done by a filament of electric bulb for 5 minutes . We know that the rate of flow of charge is called electrical current. Therefore ,

$\sf\longrightarrow Current =\dfrac{ Charge}{Time} \\\\\\\sf\longrightarrow 0.2A =\dfrac{q}{5\ min } \\\\\\\sf\longrightarrow 0.2A =\dfrac{q}{5*60s} \\\\\\\sf\longrightarrow 0.2A =\dfrac{q}{ 300s} \\\\\\\sf\longrightarrow q = 0.2 * 300 \ C </p><p> \\\\\\\sf\longrightarrow \underset{\blue{\sf Required\ Charge}}{\underbrace{\boxed{\pink{\frak{ Charge (q)= 60 \ C }}}}}$
