Current Electricity Charging Discharging Of Capacitors Question 115
Question: An ammeter, suspected to give inaccurate reading, is connected in series with a silver voltameter. The ammeter indicates 0.54 A. A steady current passed for one hour deposits 2.0124 gm of silver. If the E.C.E. of silver is $ 1.118\times {{10}^{-3}},gm{{C}^{-1}}, $ then the error in ammeter reading is
Options:
A) + 0.04 A
B) + 0.02 A
C) ? 0.03 A
D) ? 0.01 A
Show Answer
Answer:
Correct Answer: A
Solution:
$ i=\frac{m}{Zt}=\frac{2.0124}{1.118\times {{10}^{-3}}\times 3600}=0.5,A $
Therefore Error $ =0.54-0.5=0.04,A $
