A current of 0.5 A flows through a wire for 6 minutes. How much charge

1.	A current of 0.5 A flows through a wire for 6 minutes. How much charge would have passed through the wire? A) 300 C B) 30 C C) 180 C D) 1800 C
Answer» Given : Current flowing, I = 0.5 A Time for which current is flowing, t = 6 min To FIND : CHARGE passed through the wire, Q = ? Formula required : Relation between Current (I) , Charge (Q) and time (t) I = Q / t [ Where I is in Ampere, Q is in Coulomb, and t is in seconds ] Current is defined as the rate of low of Charge. SI unit of Current : Ampere SI unit of Charge : Coulomb. Solution : Converting time given in min into seconds → t = 6 min → t = 6 × 60 sec → t = 360 sec Calculating charge through the wire Using formula → I = Q / t → 0.5 = Q / 360 → Q = 0.5 × 360 → Q = 180 C therefore, Charge passed through the wire is 180 Coulomb. Hence, OPTION (C) 180 C is correct.

Answer»

Given :

Current flowing, I = 0.5 A
Time for which current is flowing, t = 6 min

To FIND :

CHARGE passed through the wire, Q = ?

Formula required :

Relation between Current (I) , Charge (Q) and time (t)

I = Q / t

[ Where I is in Ampere, Q is in Coulomb, and t is in seconds ]

Current is defined as the rate of low of Charge.
SI unit of Current : Ampere
SI unit of Charge : Coulomb.

Solution :

Converting time given in min into seconds

→ t = 6 min

→ t = 6 × 60 sec

→ t = 360 sec

Calculating charge through the wire

Using formula

→ I = Q / t

→ 0.5 = Q / 360

→ Q = 0.5 × 360

→ Q = 180 C

therefore,

Charge passed through the wire is 180 Coulomb.

Hence,

OPTION (C) 180 C is correct.
