An ammeter with an internal resistance of 510 measures a


An ammeter with an internal resistance of 51.0 ? measures a current of 5.05 mA in a circuit containing a battery and a total resistance of 1390 ?. The insertion of the ammeter alters the resistance of the circuit, and thus the measurement does not give the actual value of the current in the circuit without the ammeter. Determine the actual value of the current.
