Question

electric bulb kept for 6 hrs if its filament draws 0.3 ampere current . calculate amount of electric charge that has passed through filament​

Answer 1

Answer:

6480 C

Explanation:

charge = current* time

Answer 2

Given :

➻ Current flow in bulb = 0.3A

➻ Time interval = 6hrs

To Find :

⟶ Amount of electric charge that has passed through filament.

SoluTion :

✴ Electric Current :

⇒ Current is defined as the rate of flow of charge in other words it is a ratio of charge to the time.

⇒ Formula : I = Q / t

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

⇒ SI unit : C/s or A

⇒ Current is a fundamental quantity.

✪ Conversion :

➝ 6hr = 6hr × 60min × 60s = 21600s

➳ I = Q / t

➳ 0.3 = Q / 21600

➳ Q = 0.3 × 21600

➳ Q = 6480 C
