Figure, shows an electrolyte of `AgCI` through which a current is passed. It is observed that `2.68g` of silver is deposited in 10 minutes on the cathode. Find the heat developed in the `20 Omega` resistor during this period. Atomic weight of silver is `107.9 g mol^(-1)`. (Figure)

Text Solution

Verified by Experts

The correct Answer is:
A
`w= Zit`
`2.68 = (107.9)/(96500)xxixx15xx60`
` rArr i=3.99 = 4 amp`
`. Heat developed in the 20Omega resistor = (4)^2xx20xx10xx60`
`=16xx200xx60`
` =3200xx60 = 192000 J = 192 KJ`
