The digital voltmeter is the best basic tool for electrical troubleshooting, because it's calibrated and exact. But remember, the digital voltmeter can't detect a high-resistance fault if the circuit ...

Ningbo Joyson Electronic has been granted a patent for a programmable resistance circuit that configures selected resistances using a reference resistor. The circuit utilizes a modulated voltage ...

Pulse-width-modulation (PWM) duty cycles above 50% require a compensating ramp — called slope-compensation — to avoid instability. With traditional slope-compensation solutions, it is difficult for ...

Potential difference in series circuits Try the experiment online Resistors in series Test your knowledge Resistance ® close resistance (R)How difficult it is for current to flow. increases when ...

My last column converted an imperfect receiving device into an ideal termination using a constant-resistance network (Reference 1). The schematic in Figure 1 extends that idea, combining a good ...

Try an experiment. Next time you are in a room with someone, ask them to name everything in the room. Only certain kinds of people will say “air” or “light.” For most people, those are just givens, ...
