1. The problem statement, all variables and given/known data I understand that voltmeters are supposed to have high internal resistances so that they won't draw much current. However, they are being attached parallel to the resistor anyways and according to Kirchhoff' Law that means the voltage through both the resistor for which we are trying to measure the voltage and for the voltmeter, they will both experience the same voltage. Why does the voltmeter need to have a high internal resistance then. Isn't it redundant or unnecessary according to Kirchhoff law.
