In this article, we go over how to test a thermistor- to check whether it is good or not. Athermistoris a resistor whose resistance changes according to the temperature it is exposed to. There are 2 main types of thermistors: negative temperature coefficient (NTC) thermistors and positive te...
A capacitor is a circuit component that maintains voltage and discharges current over a matter of seconds when the voltage source is switched off. That's different from a resistor, which loses voltage virtually instantaneously compared to a capacitor. This feature of dissipating voltage slowly is ca...
To test the diode in this mode, first, the central knob of the meter must be placed where the resistor values or ohm symbol are specified on the meter. For forward bias, we have to keep the knob in low resistance (1K ohm) mode whereas, for reverse bias, we have to keep the knob ...

When working on a circuit board, it may be necessary to lift one of the leads of the resistor from the board to measure the correct resistance of the resistor. The resistance measurement displayed by a digital multimeter is the total resistance through all possible paths between the test lead...
Resistance measurements require eliminating error-inducing factors, such as residual test lead resistance, thermal electromotive force, and leakage currents in the measurement path. Learn how to address these measurement issues using a remote sense funct
One important measurement that can be made with a multimeter is a resistance measurement. Not only can these be made to check the accuracy of a resistor, or check it is functioning correctly, but resistance measurements can be required in many other scenarios as well....
Ground Resistance Tester, also generally outputs an AC power supply with a no-load voltage of 6V, and an AC source with a constant current of 10A or 25A is added between the two points to be measured. The tester can test the voltage drop between the two points, and according to Ohm's...
PROBLEM TO BE SOLVED: To provide an internal arc resistance test method for a DC high-speed switch. The method includes a test circuit construction step and a test operation. The test circuit includes a short circuit 100, a rectifier circuit 200, and an arc monitoring circuit 300. The ...
Any help would be much apricated, I’m trying to adapt this circuit to my needs. I worked out the problem myself. Typically, an RTD α is defined in units Ω/Ω/°C, however your equation for calculating the compensation resistor R2 requires α to be in units Ω/°C....
