You will be asked to perform various measurements in relation to resistors. For through-hole fixed resistors, you will require the Table below to decode the resistor value and tolerance.
Figure 2-1
Measurement of Fixed Resistance
From your kit, retrieve the resistors whose value is given in Table 2-1 below. Use the resistor color code to determine the color-code resistance and tolerance of each resistor. 
Setup the circuit in Figure 2-2. Ensure you use the 2 top-right sockets on the DMM, and it is set to measure Ω2W (ohms - 2-wire).
Figure 2-2
Measure the resistance of each resistor and record the measured value in Table 2-1. 
Compute the percent difference between the measured and color-coded values using the equation:
% difference= 𝑅measured−𝑅color code𝑅color code×100
The percent difference is shown as an absolute (positive) value for all resistors. Complete Table 2-1.
The first line has been completed as an example.
