Centrifugal Methods of reconditioning transformer oil is effective for removal of ___________.
The heat can be transferred from high temperature body to low temperature body by :
Which of the following is NOT true about diamagnetic materials-
The internal resistance of a primary cell is It generates a current of 0.2 A in an external resistance of The rate at which chemical energy is consumed in providing current in
What is the approximate strength of current that will deposit 0.5 g of silver on a spoon in 7.5 minutes? E.C.E. of silver
Silver and copper voltameters are connected in parallel to a 12 V battery of negligible internal resistance. In 30 minutes, 1 g of silver and 1.8 g of copper are deposited. At what rate, the battery is delivering energy? Given E.C.E. of and
A resistor and a silver voltameter of resistance are connected in series across a cell. How will the rate of deposition of silver be effected if a resistance of is connected in parallel with the voltameter?
One ampere current flows for one minute through a silver voltameter. It deposits 0.067 g of silver on the cathode. What is the E.C.E. of silver?
A battery of accumulators of e.m.f. 50 V and internal resistance is charged on a 100 V direct current mains. What series resistance will be required to give a charging current of 2 A?
Two electrolytic cells containing solutions of silver and gold salts respectively are connected in series to a d.c. supply. It is found that by the time 8.3 g of silver (atomic weight 108, valency 1) is deposited on one cell, 5.05 g of gold (atomic weight 197, valency 3) is deposited on another. The amount of charge that has flown during this time is
