Resistors - Oakton Community College
2-6: Resistor Troubles All experienced technicians have seen a burnt resistor This is usually caused by a short somewhere else in the circuit which causes a high current to flow in the resistor When a resistor’s power rating is exceeded, it can burn open or drift way out of tolerance
RESISTOR COLOR CODE GUIDE
RESISTOR COLOR CODE GUIDE 2 0 x10,000 10 20 x 10,000 = 200,000 1,000 = 1K Resistor = 200 K with a 10 Tolerance+-First Band Second Band Multiplier Band Tolerance Band Equation The Gold or Silver band is always placed to the right The resistor value is read from the left to right If there is no tolerance band, then find the side that has
Resistor Color Code Chart - TeachEngineering
Use the Resistor Color Code Chart (below) to understand how to use the color code system When looking at the chart, note the illustration of three round resistors with numerous color code bands The first resistor in the chart (with 4 bands) tells you the minimum information you can learn from a resistor
PULL-UP RESISTOR
Pull-up resistor limits the current Now add a pull-up resistor to limit the current that can flow through the circuit When switch S1 is open (off), pin 1 is tied to Vcc through the resistor Since pin1 is a high impedance input, a voltage meter or logic probe placed on pin 1 will show Vcc (+5v) if connected to pin 1

Resistor Testing on BOSSLASER Machines
Resistor testing is not hard, but does require some patience and requires you to be gentle with some things, such as your glass tube We are going to first be covering the resistor test on power supplies that are not the gold 60W The gold power supply does not have a test button and will require some different steps to complete a resistor test
NEUTRAL GROUNDING RESISTORS
In both types of grounding, the resistor is connected between the neutral of the transformer secondary and the earth ground, as shown in Figure 5 Transformer Secondary Line to Neutral Voltage Equals System Voltage Divided by 1 732 Neutral Line to Neutral Voltage System Voltage Neutral Grounding Resistor FIGURE 5 Where: I = Limit of Fault Current
