One of the first things you learn in electronics is how to identify a resistor’s value. Through-hole resistors have color codes, and that’s generally where beginners begin. But why are they marked ...
Younger electronic engineers may see resistors with old-style color codes to display their values a little less than those from previous years, but if there’s a shibboleth among those who wield a ...
The fun of having a giant resistor-shaped Ohmmeter is that it reads back the resistance by displaying the color code. If you’re not too hot with decoding those bands there’s a helper band to the right ...
Earlier, we already explained all about capacitors with lot of sub concepts such as types of capacitors, capacitor color code, capacitors in series and parallel circuits, capacitors applications, etc.
I once worked with an engineer that often checked his resistors with a multimeter before use. I just assumed that he was just being careful (certainly more careful than I…). Then one day, he asked me ...
Diagnosis If you have trouble seeing certain colors, an eye care professional can test for a color deficiency. Testing likely involves a thorough eye exam and looking at specially designed pictures. These pictures are made of colored dots that have numbers or shapes in a different color hidden in them.
Overview Regular urine color ranges from clear to pale yellow. But certain things can change the color. Foods such as beets, blackberries and fava beans can turn urine pink or red, for example. And some medicines can give urine vivid tones, such as orange or greenish-blue. An unusual urine color also can be a sign of a health problem. For instance, some urinary tract infections can turn urine ...
