Question

Caleulate the charge paring through an electric bulb in 30 minutes if the
value of current is 300 m.​

Answer 1

Answer:

Given,

t=30 min=30×60=1800 seconds (changing it into seconds)

I=300ma=300×10^-³A

To find.

c=?

SOLUTION:-I=Q/T

=Q=I×T

=300×10^-³×1800

=540000×10^-³

=540C [......... ANSWER......... ]

Answer 2

$\red\bigstar$Correct Question:-

•Calculate the charge passing through an electric bulb in 30 minutes if the value of current is 300mA.

⠀⠀⠀⠀⠀⠀⠀⠀

$\blue\bigstar$Calculation:-

⠀⠀⠀⠀⠀⠀⠀⠀

Let

↬Q =Charge passing through an electric bulb

↬T=Time

↬I =electric current

⠀⠀⠀⠀⠀⠀⠀⠀

Given that ,

T =30 minutes =30×60 seconds =1800 seconds

I=300 mA=300/1000 A

⠀⠀⠀⠀⠀⠀⠀⠀

Now ,

We know that Q=I×T

Q⇛300/1000×1800

Q⇛540C

⠀⠀⠀⠀⠀⠀⠀⠀

Therefore the charge required when is passes through an electric bulb =540 C

★ One coulomb is equal to the amount of charge from a current of one ampere flowing for one second. One coulomb is equal to the charge

★The ampere is a measure of the amount of electric charge passing a point in an electric circuit per unit time with 6.241 × 1018 electrons, or one coulomb per second constituting one ampere.
