Troubleshooting refrigeration equipment often requires measuring various electrical properties such as voltages, current flows, and resistances. Understanding these basic electrical fundamentals and ...

Electrical ratings are interdependent. The current through a component depends on the applied voltage (waveform and duty cycle) and the component impedance. The impedance of a component depends on the ...

Your new project requires a 14 inch trace to carry 100 mA. You can allow no more than 20 mV of drop in the wire. Will an 8 mil trace be wide enough? Your PCB copper plane uses 1 oz copper and is at ...

When more than two resistors are connected in parallel the equation becomes:\(\frac{1}{R}=\frac{1}{R}_{1}+\frac{1}{R}_{2}+\frac{1}{R}_{3}\) The supply voltage is a measure of the energy supplied to ...

Series voltage drop is the progressive loss of voltage that occurs when feeding a string of parallel-connected loads. It's of particular concern when feeding a string of roadway, walkway, or parking ...

The analysis of magnitudes and durations of touch voltages in cable installations can provide electrical professionals with a better understanding of the requirements of Art. 250 of the NEC regarding ...
