EXPERIMENT 2: RESISTANCE
OBJECTIVE
To determine the Nominal (marked) value of the resistor by using the Color Code system. Use a
multi-meter to measure the resistance value within a circuit.
REQUIRED MATERIAL
1- Multisim
BACKGROUND INFORMATION
A resistor is an electrical component that limits the flow of electrical current in an electronic
circuit. Resistors are common elements of electrical networks and electronic circuits and
electronic equipment. They are also implemented within integrated circuits. The most common
resistors are made from carbon. In this lab you will learn how to calculate and measured resistors.
