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.
