How to measure Temperature Coefficient of Resistance (TCR)? 답변: The Temperature Coefficient of Resistance, or TCR, is a measurement of a resistor's change in resistance per change in temperature. It is typically measured in ppm/°C, that is, parts-per-million change in ohms per change...

In an electrical and electronic circuit, a voltage measurement is an essential parameter that needs to be measured. We can measure the voltage between a particular point and the ground or zero-volt line on a circuit. In a 3-phase circuit, if we measure the voltage between any of one phase...
Best way to measure the sound quality of the speaker To measure sound quality, manufacturers use a standard test for installing a microphone linked to a decibel meter. One meter in front of a speaker and measuring the sound pressure level output, in decibels, with one watt of power given in...
You can calculate ohms from volts and amps or watts, but you can't convert volts to ohms since volt and ohm units do not measure the same quantity.Volts to ohms calculation with ampsAccording to ohm's law, the resistance R in ohms (Ω) is equal to the voltage V in volts (V) ...
2. Turndial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes (continuity, capacitance or diode; see illustration below). 5. Connect test leads across the component being tested. ...
To measure resistance: 1. Turn power to circuit OFF. If a circuit includes a capacitor, discharge the capacitor before taking any resistance reading. 2. Turn digital multimeter dial to resistance, or ohms, which often shares a spot on the dial with one or more other test/measurement modes ...
Set your multimeter to measure AC voltage. A 200V range is appropriate for household (120V) electrical outlets, or you can use a 20V range for increased precision. Connect the appropriate test cables of your multimeter to the corresponding hot and neutral terminals of the outlet, making sure ...
For common desktop computer's ATX PSU, there is already a documented standard on how to measure the noise & ripple, and as David pointed out, using a differential probe is the recommended tool. Its clearly documented the measurement details here ->ATX12V Power Supply Design Guide ...
You may be able to solve the problem temporarily by pinching off the splinters with pliers and lightly filing the plastic smooth, but this is just a stopgap measure; the agitator should be replaced. Replace a damaged agitator with a new one of the same type. To do this, unscrew the cap...
