An ammeter and copper voltmeter are connected in aseries in an electric circuit through which a constant direct current flows. The ammeter shows `0.525` ampere. If `0.6354 g` of `Cu` is deposited in `1` hr, what is the percentge error of ammeter ? `["At. wt. of "Cu = 63.54]`

An inaccurate ammeter and silver coulometer connnected in series in an electric circuit through which a constant direct current flows. If ammeter reads 0.6 ampere throughout one hour, the silver deposited on coulometer was found to be 2.16 g . What % error is in the reading of ammeter? Assume 100% current efficiency.
