Question

A service station charges a battery using a current of 67-A for 5.0h .How much charge passes through the battery?​

Answer 1

Given:-

• Current ,I = 67 A

• Time taken ,t = 5 h = 5×60 ×60 = 18000 s

To Find:-

• Charge Passes through the battery ,Q

Solution:-

As we know that Current is defined as the flow of charges per unit time .

• I = Q/t

Where,

I is the Current

Q is the charge

t is the time taken

Substitute the value we get

→ 67 = Q/18000

→ Q = 67 × 18000

→ Q = 1206000

→ Q = 1.2 × 10⁶ C

Therefore, the charge passes through the battery is 1.2 × 10⁶ Coulombs .

Answer 2

Answer:

Given :-

• Current (I) = 67 A
• Time taken (T) = 5 h = 18000 s

To Find :-

Charge pass (Q)

SoluTion :-

As we know that,

$\huge \boxed { \tt \: I \: = \frac{Q}{t}}$

I = Current

Q = Charge

T = Time

$\sf \: 67 = \dfrac{Q}{18000}$

$\sf \: Q \: = 67 \times 18000$

$\sf \: Q \: = 1206000$

$\sf \: Q= 1.2 \times {10}^{6} c$
