Question

If a toy fan is connected across a battery for 2 minutes and we know tha a charge transfer of 120 c takes place then find out the current in the circuit for that period of time?​

Answer 1

2 min = 120 sec

Current = Charge/Time

= 120/120

= 1 A

Answer 2

Given that, a toy fan is connected across a battery for 2 minutes.

{ Time (t) is 2 minutes }

Also given that, 120C of charge transfers.

{ Charge (q) is 120C }

We have to find the current in the circuit.

Now,

Current = Charge/Time

First of all, convert the minutes in seconds

1 min = 60 sec

2 min = 120 sec

Therefore,

Current = 120/120 = 1A

Additional Information

→ Rate of flow of charge is known as Current. And it's S.I. unit is Ampere (A).

→ Charge: It is an inherent property of matter due to which they attract or repel each other.

Charges are of two types positive and negative. It's S.I. unit is Coulomb (C).

Like charges repel each other and unlike charges attract each other

→ Time: What a clock reads. It's S.I. unit is Second (sec).
