For the network shown, calculate the expected current Ii, Iz, and I3. Construct the circuit, then measure and record the actual currents. Compare them to your calculations. Why might they be different?

For the voltage divider network shown, calculate the output voltage. Measure and record the voltage with a voltmeter. Is it different from the calculated value? Why or why not? Now replace the 1K and 3.9K resistors with 1M and 4M resistors. How is the measurement different from before? Estimate the voltmeter's internal resistance. What should it be ideally? 3.9K
