Answer 1

Answer: B. 120 C

→I=q/t

→2=q/60

→q=120C

Answer 2

Given:

• Current = 2A
• Time = 1 min

To Find:

• The value of charge flowing in one minute.

Solution:

The formula to find charge is given by,

I = q/t  → {equation 1}

Where, "q" is the charge, "I" is the current, and "t" is the time.

The time given is one minute which we are converting to seconds by multiplying it by 60 secs.

∴ t = 1×60 = 60 secs.

On substituting the values in equation 1 we get,

⇒ 2 = q/60

We rearranged the above equation in terms of "q".

⇒ q = 60×2 {multiplying the terms}

⇒ q = 120 C

∴ The value of the charge flowing in one minute = 120 C
