Question

If a current of 10 A flow for four minutes find the quantity of electricity transfer

Answer 1

Answer:

We already know that,

I=Q/t

Here,

Current=10A

Time=4minutes=4*60=240 seconds

So, finding Q.

10=Q/240

⇒2400 C=Q

Answer 2

Given,

A current of 10 A flows for four minutes.

To Find,

The quantity of electricity transfer =?

Solution,

We can solve the question as follows:

It is given that a current of 10 A flows for four minutes. We have to find the quantity of electricity transfer.

$Current = 10\: A$

$Time = 4\: minutes$

Since the time is not in S.I. units, unit conversion is required. We will convert minutes into seconds.

If one minute is equal to 60 seconds, then 4 minutes will be equal to 240 seconds.

$1\: minute = 60\: seconds$

$4\: minutes = 60*4 = 240\: seconds$

Now,

The quantity of electricity transfer will be equal to the charge Q that flows.

The formula for calculating the charge is given as:

$I = \frac{Q}{t}$

or

$Q = It$

Where, $Q = Charge$

            $I = Current$

            $t = Time$

Substituting the values in the given formula,

$Q = 10*240$

$Q = 2400\: C$

Hence, the quantity of electricity transfer is 2400 C.
