Industrial Automation, PLC, VFD, and Troubleshooting
Introduction
Every industrial automation system is built on four fundamental electrical concepts:
Voltage
Current
Resistance
Power
These four concepts explain why a sensor works, why a relay energizes, why a motor turns, and why electrical components …
