Question

a current of 150 ma is flows through a corcuit for 2 min. find the amount charge that flows through the circuit.

Answer 1

Answer:

$q = it$

Explanation:

q=it

$i = 150 \times {10}^{ - 3} ampere \\ \\ i = 0.15ampere \\ t = 2 \times 60 = 120secons$

q= 0.15*120

q=18ampere

Answer 2

$\bf{Correct\:Question}$

A current of 150 mA flows through a circuit for 2 min. Find the amount of charge that flows through the circuit.

$\bf{Solution :-}$

Given, Current, I = 150 mA = 150 × 10-³ A

Time, t = 2 min = 2 × 60 = 120 second

Amount of charge, q = ?

$\rm{We\: know \:that, \:q = I\times\:t}$

$\longrightarrow\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\bf{q=150\times\:10^{-3} \times 120}\\ \\ \longrightarrow\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\:\bf{q=\:18\:C}$

So, 18 C of charge flows around the circuit.
