Procedure:
A. Voltage/Current relationship in a Series Circuit.
1. (a) Measure the resistance (using an Ohmmeter) of each of the two resistors:
Rx (220 Ohm resistor , color code: red - red - brown)

Meter resistance = 88.6 ohms.
Now, set up the circuit in Fig. 4. Connect the
meter leads so that the meter pointer deflects
toward the right.
The meter pointer should deflect exactly to the
right edge of the scale.
