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

➠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

Answer 2

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= $\frac{Q}{t}$

• I denotes current 

• Q denotes charge 

•t denotes time 

Sl unit : C/s or A 

Current is a fundamental quantity. - Conversion : 6hr = 6hr x 60min x 60s = 21600s 

 I = $\frac{Q}{t}$ 

 0.3 = Q/ 21600 

 Q = 0.3 x 21600 

 Q = 6480 C
