c) Obtain a digital multimeter (DMM), a variable voltage supply, and two resistance boxes. Set the voltage supply to 10 V and connect the boxes in series across it; set the boxes to 1 MΩ
. Using the voltmeter measure the voltage across each box. It should happen that Kirchhoff’s loop law appears to be violated. This is due to the voltmeter having an internal resistance. Record your voltage readings and use them to estimate this resistanc
