Question

A current of 6A flows through a conductor for 2 s . (i) Calculate the amount of charge passing through the conductor. ​

Answer 1

Given:-

• Current ,I = 6 A

• Time taken ,t = 2 s

To Find:-

• Amount of Charge ,Q

Solution:-

As we know that Current is defined as the Charge passing per unit time.

• I = Q/t

where,

I is the Current

Q is the Charge

t is the time taken

Substitute the value we get

→ 6 = Q/2

→ Q = 6×2

→ Q = 12 C

Therefore, the charge passing through the conductor is 12 Coulombs .

Additional Information !!

Potential Difference: The potential difference between two point in an electric circuit carrying some current as the work done to move a unit charge from one point to the other.

Potential difference = Work done /Charge.

• V = W/Q

here

V is the potential difference

W is the work done

Q is the charge

✧ SI unit of electric potential energy is volt (V).

✧ 1 volt : The potential difference between two points in a current carrying conductor when one joule of work is done to move a charge of one coulomb from one point to other.

1 Volt = 1Joule/1Coulomb

Answer 2

Answer:

$\huge \bf \: Given$

Current (I) = 6A

Time taken (T) = 2 s

$\huge \bf \: To \: find$

Amount of charge

$\huge \bf \: Solution$

As we know that

$\huge \bf \: I \: = \frac{Q}{T}$

Here,

• I = Current
• Q = Charge
• T = Time taken

Putting values

$\tt \: 6 = \dfrac{Q}{2}$

$\tt \: Q \: = 6 \times 2$

$\tt \: Q = 12$

Therefore, the amount of charge is 12 coulombs.
