RESISTOR Measurement Tutorial | Color Code, Direct, Indirect | Online Lecture "Electronics"
How do resistor color codes work? How can you measure the value of a resistor? What is the difference between direct and indirect measurement? How to use a multimeter? What are typical errors when measuring resistance? What is a current-voltage characteristic and how can you use it to improve measurements? In this video I will answer these questions for you!
Resistors are among the most frequently used components in electrical engineering. You can use them to limit the current flow in a circuit, you can split the current or voltage in a controlled way and you can also, for example, pull the input voltage on a chip to a desired level using a pull-up resistor. There are many more applications, but for most of them, you need to make sure that the actual component you want to put on your circuit board is as close as possible to its required theoretical value - which might not always be the case, either because of tolerance deviations or because a resistor has been sorted into the wrong box.
And to make sure you always pick the right component, we will now look at three ways to determine resistor values: (1) First, we will use the resistor color code. (2) Then, we will take a direct measurement with a single multimeter and (3) finally an indirect measurement with two separate multimeters, one for current and the other one for voltage.
The video is well suited for university study and training in the fields of electrical engineering, electronics and other MINT subjects.
