Homework Statement
In the circuit shown, a student mistakenly connects a perfect ammeter(i.e. One of negligible resistance), in parallel with one of two identical resistors. The ammeter reads 0.40A.
What would the reading have been if he had correctly connected the ammeter in series with the two resistors? The cell also has negligible resistance.
