Find what percentage error would be made

Reference no: EM13660301

A cell of emf 3.0 volts and internal resistance of 0.01 Ω is connected through an ammeter of 0.05 Ω internal resistances to a 5.0W rheostat by wire having a total resistance of 0.85 Ω. In the calculation of the current, find what percentage error would be made by neglecting all resistances except that of the rheostat?
