Question

find the amount of current flowing through a conducting material when 360c charge flows for 3 min

a) 2.5 a
b) 5a
c) 2 a
d) 3 a​

Answer 1

Answer:

A charge Q of 300C is drawn by electric bulb for time 5 minutes.

If a net chargeQ, flows across any cross-section of a conductor in time t, then the current i, through the cross-section is , i=

t

Answer 2

Required Answer:

Option C ✔

_______________________________

Given:

• Charge flowing ( Q ) = 360 C

• Time taken ( t ) = 3 min = 180 seconds

Converting to its standard form:

→ 1 min = 60 seconds

→ 3 min = ( 60 × 3 )sec

→ 3 min = 180 seconds

_____________________________

To calculate:

• Amount of current flowing through it. ( I )

______________________________

Formula used:

• I = Q/t

Where,

◆ I = current

• SI unit of current is Ampere.
• Ampere is denoted by 'A'

◆ Q = charge

• SI unit of charge is Coulomb.
• Coulomb is denoted by 'C'.

◆ t = time

• SI unit of time is seconds.
• Seconds is denoted by 's'.

______________________________

Calculation:

Substituting all the value in the formula of current.

→ I = Q/t

→ I = 360/180

→ I = 2

→ I = 2 A

Therefore, the amount of current flowing through a conducting material is 2 Ampere or 2 A.

So, option C is correct ( 2 A )
