A copper voltameter is connected in series with a heater coil of resistance 
. A steady current flows in the circuit for twenty minutes and mass of 0.99 g of copper is deposited at the cathode. If electrochemical equivalent of copper is 0.00033 gm/C, then heat generated in the coil is
Text Solution
Verified by ExpertsThe correct answer is:
A
m = Z i t ⇒ ⇒ 
Hence heat generated in the coil is
= 750 J
