Question

A dry cell can supply a charge of 300 c . If current drawn from cell is 600 mA, find the time in which cell discharges.​

Answer 1

Explanation:

See there is a total amount of 300 C of charge in the battery. Now current drawn in 600 mA which equals 0.6 A. current means the amount of charge taken out in 1 second. time = 300/0.6 = 5000 s.

Answer 2

Given:

⠀⠀

⠀⠀

• Q = 300 C
• I = 60 mA

⠀⠀

⠀⠀

where Q is Charge anf I is Current

⠀⠀

To find:

⠀⠀

⠀⠀

Time in which cell discharges.

⠀⠀

⠀⠀

Solution:

⠀⠀

⠀⠀

We know that,

⠀⠀

I = Q/t

⠀⠀

$\implies$ t = Q/I

⠀⠀

$⟹t \: = \frac{300 \times 1000000}{60} \\ \\ = 5000000 \: s$

⠀⠀

5,000,000 s means 1388.88 hours

⠀⠀

Thus, the time in which cell discharges is 1388.88 hours.
