When the maximum resistance of the sliding rheostat is approximately equal to theresistance of the resistorto be measured, a voltage divider circuit must be selected. When measuring with a voltmeter (ammeter), one must ensure that the measured data cannot exceed the maximum measurement value of th...
First of all, you need to choose the resistance value. To do that you useOhm’s law. One common example is tofind the resistor value you need for an LED. Next, you need to consider the power that the resistor needs to dissipate. Power dissipation in a resistor can be calculated with ...

Step 1: Double Confirm the Resistance of the Resistor Even thought the value of the resistance is printed, you still need to confirm whether the actual resistance is the same as shown. Most resistor has 10% tolerance in their actual value, but it still depends on the type of resistor you ...
and the operating temperature range. This defines the accuracy of the RTD starting with a base resistance of 100 Ω at a temperature of 0°C. There are different standard tolerance classes for DIN RTDs. These tolerances are shown in Table 2, and they also apply to Pt1000 RTDs...
The legs of R1 and R2 go into the same row of the breadboard. Into R1 we supply 5V and into R2 we connect to GND. Where the legs of R1 and R2 meet is the output voltage, which should be 3.4375V, well within the tolerance of the 3.3V GPIO. (Image credit: Tom's Hardware) The...
There are fancy multimeters that areautoranging, meaning they automatically change their internal range to attempt to find the correct voltage, resistance, or current of the thing you're poking at. Auto-ranging can be very helpful if you know how to use it. Generally speaking, autoranging mult...
When in doubt, check the datasheet or use a multimeter to measure the actual resistance. Other Resistor Markings While color coding is the most common, resistors may also be marked in other ways: Multiplier written numerically such as 10M or 10MΩ for 10 million ohms Tolerance written out ...

A tolerance of 10% on a 100 ohm resistor means that the resistance can be anywhere from 90 to 110 ohms. Color Value Brown ±1% Red ±2% Orange ±3% Yellow ±4% Green ±0.5% Blue ±0.25% Violet ±0.10% Gray ±0.05% Gold ±5% Silver ±10% The least tolerance in typical resistors ...
