Given:
Mass of silver deposited, m = 2.68 g



Time, t = 10 minutes = 600 s


Using the formula, from faraday’s law of electrolysis –



where,


m = the mass of the substance deposited on the electrode


z=electrochemical equivalence


i=current passing


t=time taken






Now, heat developed in the 20 Ω resistor from Joule’s heating effect,



Where


I is the current in the circuit


R is the resistance of the resistor


T is the time period for which the current is allowed to flow through the circuit


Putting the above values in the formula, we get
