Experiment - Current and Ohm's Law

 
  1. Assemble the circuit in Figure gif using the same voltage setting on the power supply and the same resistor as previously measured.
  2. Set the multimeter to measure dc current, make sure that the leads are correctly set for current measurement.
  3. Measure the current flowing through the resistor. Does this value agree with Ohm's Law ()?
  4. Measure the current flowing through the resistor in the opposite direction. This is done by reversing the leads of the ammeter. Does this value agree with Ohm's Law ()?
