Question

if a current of 10 A flows for 4 minutes find the quantity of current​

Answer 1

Answer:

Current is the rate of flow of charge . Hence, 2400 Coulombs charge is transferred when current of 10A flows for 4 min .

Answer 2

Quantity of charge = 2400 C

Given

A current of 10 A flows for 4 minutes

To Find

Quantity of charge

Knowledge Required

Current is defined as charge acting per time

$\bf I=\dfrac{Q}{t}\\\\ \bf \pink{\bigstar\ \; Q=It}$

where ,

• Q denotes charge
• I denotes current
• t denotes time

SI unit of charge is Columb

SI unit of Current is Ampere

SI unit of time is Second

Solution

Given ,

• I = 10 A
• t = 4 min = 4 × 60 = 240 s
• Q = ? C

Apply formula ,

⇒ Q = It

⇒ Q = (10)(240)

⇒ Q = 2400 C  $\green{\bigstar}$

So ,

Quantity of charge = 2400 C
