Question

a current of 0.5 is drawn by a filament of an electronic bulb for 15 minutes find the amount of electrical charge that flows through the circuit
​

Answer 1

$\huge{\mathcal{\blue{Answer}}}$

$\large{current=charge/time}$

The amount of charge drawn in 15minutes

$0.5ampere = \frac{charge}{15mins}$

Answer 2

Answer:

A current of 0.5 is drawn by a filament of an electronic bulb for 15 minutes, the amount of electrical charge that flows through the circuit will be $450C$

​

Explanation:  

• From the question,

      Current, $I =0.5A$

      Time, $t = 15 min = 15\times 60 = 900s$

• Let I be the current flowing through an electrical circuit t be the time of flow and Q be the total charge.  

        We have the expression for the total charge as,

        $Q = It$     ...(1)

        We can use this equation for solving the given question.

        Then,

        Substituting these values into equation (1)

        $Q = 0.5\times 900= 450C$
