Those bands tell you the value of the resistor. Before you can decode the resistor value, you need to know a little more about resistors. There are two main types of resistors: Standard resistors have four color bands. Three of the bands tell you the nominal value, which means the value...
How did you do? With practice, you will be able to read resistor codes effortlessly. Common Mistakes Here are some common mistakes to avoid when decoding resistor color codes: Forgetting the multiplier – Make sure to apply the multiplier band or else your value will be way off. ...
Combine the values of the different bands to find the one value. So, if you have a four band resistor with the colors red, blue, yellow and brown, you’ll know that your digit value is 26. The yellow is the multiplier and that’s 1000. So, you’ve got 26,000 Ohms. However, sin...
all you need to do is to multiply the temperature coefficient with the resistance of the resistor, and then divide it by a million. This will give you a value in ohm/ºC which tells you how much the resistance will drop with every degree...
Also, as the output data is 24-bit, your code will need to be properly sign-extend the conversion result to a signed 32-bit value. Last thing, in your print statement you are printing the return value of the ADC.rdata() function instead...

If you are using a DMM, you'll find it easier to understand the readout. It will be in ohms, K ohms or M ohms. If you have set the scale where the upper end of the range is below the resistor value, you will see either a flashing display or sometimes OL for "over limit." Tu...
A megohmmeter employs very high voltages for insulation resistance testing, reaching up to 5000 V. Consistently adhere to established protocols and safety regulations. Upon conducting insulation resistance testing with a megohmmeter, connect the tested device to ground via a 5 kW, 5 W resistorif the...
If you want to understand how the capacitor works without reading theory and formulas – then build this circuit: You can use a 9V battery, a standardLight-Emitting Diode (LED), and a 1000 µF capacitor. The resistor value can be around 500-1000 ohms. ...
