Question

a current of 5a is drawn by a filament of an electric bulb for 50 min.find the amount of electric charge .that flows thought the circuit​

Answer 1

Given :

Current flow = 5A

Time interval = 50 min

To Find :

Amount of electric charge flows through the circuit$.$

Solution :

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

Mathematically, I = Q/t

• It is a scalar quantity having only magnitude.
• SI unit : A (ampere) or C/s
• Dimension formula : [A¹]
• Electric current is a fundamental physical quantity.

First of all we need to convert unit of time into second.

We know that, 1 min = 60 s

∴ 50 min = 50 × 60 = 3000 s

By substituting the given values;

➠ I = Q/t

➠ 5 = Q/3000

➠ Q = 3000 × 5

➠ Q = 15 × 10³ C

Answer 2

Answer:

Given :

Current flow = 5A

Time interval = 50 min
