4)resistor tolerance, i will change to smaller ones like 0.1% to check. 5)R38 R39 , it is used to calc the dc line current. it is a integral circuit. 6)R26 R28 , for one application which need different voltage bias. at last,thanks for y...
They cost less than 1 cent each, but humble resistors are an essential tool no matter what electronics you are building. In this reference guide we look at using them in projects, and how to identify the correct resistor for your project.
First and foremost, we must give power to the chip. We will feed it 5V of power, so we give +5V to pin 14 and we connect pin 7 to GND. This establishes power to the chip. Next we connect pull up resistors to each of the inputs of the NAND gate. A pull up resistor circuit f...
To check the reference voltage, the reference detect function will indicate that the reference voltage is too low. The customer can also select the internal reference as an analog input so this could be used to monitor the voltage generated across the external reference resistor. This assumes that...
So it's easy to see now how any voltage can be obtained with a resistor voltage divider circuit. To check calculations for voltage dividers, see theVoltage Divider Calculator. This way, you can check calculations you've made to see if they are correct and accurate. This voltage divider calc...

How to Choose Capacitors Capacitors are utilized in different circuits. Choosing the component of your capacitor for your PCB design using just the value for the capacitance is not usually enough in the majority of applications. Just like the resistor components, the capacitors also possess tolerance...
Cut it, strip the wires and hook in the battery and resistor as shown. (Most cheap phone cords contain only two wires, but if the one you buy happens to have four, then use the center two.) When two people pick up the phones together, they can talk to each other just fine. This...
Method 1: Testing a Capacitor with Resistor mode in a Multimeter To monitor the circuit, it is necessary to have live data for values like voltage, current, power, and more. For that, there are a number of measuring devices like digital multimeters which is the best option while troubleshoot...
