When an electric current passes through the body, it can cause three main effects: When it comes to current, DC becomes hazardous at around 130 milliamps (mA)—a seemingly small amount, especially ...
HISTORY: High Resistance Grounding is a means of limiting ground fault current in electrical systems. Unrestrained fault current can cause severe equipment damage, product destruction, and personnel ...
You've heard it before: current kills. Image source: YouTube. As an electrical engineer, you’re likely familiar with the safety tip that goes, “It’s not the voltage that kills you, it’s the current.” ...
Multimeters. They've been described as the tape measure of the new millennium. But what exactly is a digital multimeter (DMM) and what can you do with it? How do you make measurements safely? What ...
Modern digital multimeters (DMMs) are user-friendly, accurate, and safe — when used correctly! Reading voltage is simple, but measurements must be properly interpreted. With a clamp-on DMM, accurate ...
