Answer 1

Given:-

• Current ,I = 0.8 A

• Time taken ,t = 20min = 20×60 = 1200 s

To Find:-

• Electric charge ,Q

Solution:-

Charge is defined as the product of current and time .

• I = Q/t

Where,

I is the current

Q is the Charge

t is the time taken

Substitute the value we get

→ 0.8 = Q/ 1200

→ Q = 1200 × 0.8

→ Q = 120 × 8

→ Q = 960 C

Therefore,the electric charge passing through the circuit is 960 Coulombs .

Answer 2

Answer:

Given :-

Current = 0.8 A

Time taken = 20 min = 1200 sec

To Find :-

Electric charge

SoluTion :-

As we know that charge is the product of time and current.

$\sf \therefore \: Q = 0.8 \times 1200$

$\sf \: Q = 8 \times 120$

$\sf \: Q = 960 C$

$\huge \bf current \: = 960 \:$
