(8%) Problem 5: An ideal ammeter would measure electric current without altering it. A physical ammeter always has some internal resistance which has a small effect on the current. Suppose that you are given an ammeter which has an internal resistance of Rint=35.7 and a full-scale reading of 775A . To use the ammeter with larger current, parallel resistance is addedWhat resistance, in ohms, would you place in parallel with the ammeter so that a full-scale reading corresponds to an input current of I=55.5mA
