Fig 2. The schematic of the secondary-voltage tester includes an array of voltage dividers (r3-r11) that can be switched in or out of the circuit to test for a range of voltage deviations.

We spent eight months talking with electricians and testing seven models to find the best and safest non-contact voltage testers. Here’s what we discovered.

Commercial crystal testers are however very expensive, that is why this simple electronic crystal tester was born. The transistor T1 and the crystal to be tested together makes a complete crystal ...

Stackpole recently introduced its RVCU Series high voltage chip resistors, providing design engineers, machine builders and OEMs working with high-voltage ...

A voltage divider is one of the easiest circuits in the world to analyze. Consider two resistors Ra and Rb in series. Voltage comes in at the top of Ra and the bottom of Rb is grounded.

[Ken] needed to supply 3.3 volts of regulated power. He started by using a linear voltage regulator but after a few calculations he discovered that 72% of what he put in was lost to heat.

A potential divider, also known as a voltage divider, is a simple yet essential circuit used to reduce voltage to a desired level. It consists of two resistors connected in series close series A ...
