Question

A current of 80 micro ampere is drawn by a device for 100 days. find how many farads involved in this process

Answer 1

Answer:

A current of 80 micro ampere is drawn by a device for 100 days. find how many farads involved in this process

Answer 2

Answer:

$8.9547\times10^{-5}$ Faraday charge flowed through the device in 100 days.

Explanation:

The current drawn is 80 microampere.

The total time taken is 100 days.

Total time taken in seconds = 100×24×60×60

Total time taken in seconds = 8640000 seconds

Now, calculating the total charge that flowed through the device

$\[\begin{gathered} I = \frac{Q}{t} \hfill \\ {10^{ - 6}} = \frac{Q}{{8640000}} \hfill \\ Q = {10^{ - 6}} \times 8640000 \hfill \\ Q = 8.64C \hfill \\ \end{gathered} \]$

As we know that,

1 Faraday = 96485.3C

1C = $\frac{1}{96485.3} \ Faraday$

8.64C = $8.64\times\frac{1}{96485.3} \ Faraday$

8.64C = $8.9547\times10^{-5}$

Therefore, $8.9547\times10^{-5}$ Faraday charge flowed through the device in 100 days.
