Question

5. How long would it take for 2000 coulombs of charge to flow through a motor if the current is 2.5A?

Answer 1

$\qquad \qquad\huge \underline{\boxed{\sf Answer}}$

As we know,

$\sf \:currrent = \dfrac{charge}{time}$

where,

• Charge is in Coulombs

• Time is in seconds

• Current is in Amperes

Let's use the given formula ~

$\qquad \sf  \dashrightarrow \: 2.5 = \dfrac{2000}{t}$

$\qquad \sf  \dashrightarrow \: t= \dfrac{2000}{2.5}$

$\qquad \sf  \dashrightarrow \: t = \dfrac{2000 \times 2}{2.5 \times 2}$

$\qquad \sf  \dashrightarrow \: t = \dfrac{4000 }{5 }$

$\qquad \sf  \dashrightarrow \: t = 800$

So, the Total time taken by the Charge to flow through a motor is 800 seconds

Or it can be converted into minutes as :

• $\qquad \sf  \dashrightarrow \: \dfrac{40}{3} \: \: or \: \: 13.33 \: \: min$
