4.2 Using the resistor in a circuit 1. Connect the cireuit shown in Figure 3 below. Set the power supply at 10V and select Ri equals to (2.2k). 2. Turn off the power supply. Change the value of resistor R2 and measure it using the ohmmeter. Write your reading in the table shown in Figure 4. 3. Measure the voltages across R; and Ra and write the readings in the table. 4. Repeat the steps above for another two different values of R2 and write your readings in the table.

![Experiment no. 2: Using Variable Resistors
Prepared by: Dr. Ali Al-Hashimi
Department of Medical Instrumentation Techniques Engineering

1 Objective
The objective of this experiment is to understand and learn how to use a variable resistor, be familiar
with measuring its value, and using it in cireuits.
Introduction
A variable resistor is an electric/electronic component that can be used to vary the amount of current
and/or voltage within a circuit. A variable resistor, which can also be called a potentiometer, can
provide multiple values of resistance between zero and its maximum value. This could be done, for
example, by sliding wiper contact along a track or by rotating a knob.
Figure la shows two symbols used for variable resistors. Figures lb and le show two types of
potentiometers. Variable resistors can be usod in different applications, such as circuits for voice
control, voltage divider, or dimming lighting.
