Question

calculate the current supplied by a cell if the amount of charge passing through the cell in 2 minutes is 240 column​

Answer 1

Given :

Charge flow = 240C

Time interval = 2min

To Find :

Current supplied by cell$.$

Solution :

★ Electric current is defined as the rate of charge flow per unit time in the conductor.

Mathematically, [I = Q / t]

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

It is a scalar quantity having only magnitude.

SI unit : A (ampere)

★ Conversion :

We know that 1min = 60s

∴ 2 min = 2 × 60 = 120s

By substituting the given values;

➠ I = Q / t

➠ I = 240/120

➠ I = 2A

Answer 2

Given:-

⌬ Time = 2 minutes

⌬ charge flow = 240 column

To find:-

⌬ Current supplied by a cell.

Solution:-

Formula- $\sf\pink{⟶}$ $I = \sf{\dfrac{Q}{t}}$

⠀⠀⠀⠀ ⠀$\sf\purple{⟶}$ $Current = \sf{\dfrac{Charge}{time taken}}$

$\sf\red{⇝}$ $\sf{1 min = 60 seconds}$

$\sf\green{⇝}$ $\sf{∴ 2 min = 2 × 60 = 120s}$

$\sf\blue{⇝}$ $I = \sf{\dfrac{Q}{t}}$

$\sf\pink{⇝}$ $I = \sf{\dfrac{240}{120}}$

$\sf\red{⇝}$ $I\sf{ = 2A}$
