Using a Bread Board
and variable power supply, construct the circuit shown below. Use a digital multimeter to measure
IT, VR1, VR2, & VR3.
Remember, unlike measuring voltage, the current measurement is an intrusive
measurement. This means that you must temporarily modify the circuit. Redirect the current through
the DMM and then direct it back to the circuit.
In this activity you will alternately measure
voltage and current with the same DMM. Be sure that the meter is in the proper mode for what is being
measured before the power is applied.
This circuit was analyzed by hand in your circuit theory
assignment and simulated in your circuit theory using multisim assignment. How do these measured
values compare to the previously calculated and simulated values? If they do not match, review your
circuit, your calculations, and make any necessary corrections.
