Question

how much charge is needed to flow 2A current for 2 minutes​

Answer 1

Answer :-

Charge = 240 C

Explanation :-

Analyzing the question,

Given:

• Current (I) = 2 Ampere
• Time (t) = 2 minutes

To find:

Charge = Q = ?

Solution:

Electric current is defined as the rate of electric charge flowing in a conductor in a particular time interval.

So,

I = Q ÷ t

Firstly convert time which is given in minutes into its S.I unit i.e. Seconds

2 minutes = 2 × 60 = 120 seconds

Substitute the known values.

2 = Q ÷ 120

⇒ Q = 2 × 120

⇒ Q = 240 Coulombs

∴ Charge needed to flow 2 Ampere current for 2 minutes = 240 Coulombs

SOME IMPORTANT FORMULAS IN ELECTRICITY:

• Q = ne
• V = I × R (Ohm's law)
• H = I²Rt (Heating effect of current)
