Q: The left taillight on my pickup is somewhat dimmer than the one on the right side. It’s not bad enough to go through the trouble and expense of having fixed it. But it bugs me. Any chance you have ...

With the increasing use of aftermarket electrical devices on older muscle cars, this amplifies the demand for sufficient ...

We have all had difficulty testing diodes in-circuit. Most DMM’s have a diode Vf function that measures forward drop, but what is the normal voltage drop? Analog VOM’s attempt to measure resistance of ...

Voltage Drop TestingMany common electrical difficulties can be diagnosed by using a simple voltage drop test to discover the root of the problem. The voltage drop test is a dynamic test intended for ...

In-circuit test (ICT) has been instrumental in identifying manufacturing process defects and component defects on countless varieties of populated printed circuit board (PCB) assemblies for more than ...

The NEC provides a recommendation on voltage drop for branch circuits in Informational Note No. 4 following 210.19(A). A similar recommendation for feeders exists in Informational Note No. 2 following ...

Any engineer testing electronic devices cares about accuracy, which depends on the DC programmable power supply’s specifications, how it monitors the output, and how it’s wired to the device being ...

Sample-and-hold amplifiers sample an analog voltage and hold it until an ADC can digitize it. A perfect sampling circuit holds a voltage until digitizing is complete. Thus, the amplifier’s output is ...
