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

Calculate the total resistance of the circuit. Calculate the current flowing in the \({3}\Omega\) resistor. Calculate the voltage across the \({8}\Omega\) resistor. Calculate the current flowing in ...

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 ...

When you determine conductor sizes for low-voltage feeder or branch circuits, do you account for voltage drop? Some people believe this is unnecessary, and some believe that doing so is a Code ...

When you need a multimeter for testing electrical equipment around the home, it's vital to know what all those symbols around the dial mean.

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 ...

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 ...

Shini explores electric current, voltaic cells, and how we get electric charge. Electric current works like a river... kinda... Instead of flowing based on elevation ...

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 ...
