6 steps

To connect the circuit for measuring voltage and current across an unknown resistor, as implied by your previous question, follow these steps:

  1. Connect the power supply and switch.

    Connect the positive terminal of the power supply to one terminal of the switch.

  2. Connect the ammeter in series.

    Connect the other terminal of the switch to the positive terminal of the ammeter. The ammeter measures the current flowing through the circuit and must be connected in series.

  3. Connect the rheostat in series.

    Connect the negative terminal of the ammeter to one terminal of the rheostat (variable resistor). The rheostat allows you to change the current and voltage in the circuit.

  4. Connect the unknown resistor in series.

    Connect the other terminal of the rheostat to one terminal of the unknown resistor.

  5. Complete the series circuit.

    Connect the other terminal of the unknown resistor back to the negative terminal of the power supply. This completes the main series circuit.

  6. Connect the voltmeter in parallel.

    Connect the positive terminal of the voltmeter to the side of the unknown resistor that is connected to the rheostat. Connect the negative terminal of the voltmeter to the other side of the unknown resistor. The voltmeter measures the voltage across the resistor and must be connected in parallel.
