🔥 How to Build a HIGH VOLTAGE PROBE | Measure 1000V+ Safely – in සිංහල ⚡
මෙම වීඩියෝවෙන් මම පැහැදිලි කරන්නේ 1000V කට වැඩි වෝල්ටේජ් මැනීමට හැකි High Voltage Probe එකක් සාදාගන්න ආකාරය ගැනයි.
වෘත්තීය Probe එකක් මිලදී ගැනීමට ඩොලර් 100 කට වඩා වියදම් වෙනවා — නමුත් මෙය ඔබට අතිශය අඩු මුදලකටම සාදාගන්න පුළුවන්!
මෙහිදී මම විස්තර කරන්නේ Voltage Divider Circuit එකේ මූලධර්මය, එහි ප්රායෝගික නිමාව සහ සුරක්ෂිතව වැඩ කිරීමේ ක්රමය ගැනයි 🔧
🔧 In this video, I explain step by step how to build a DIY High Voltage Probe that can safely measure voltages over 1000V using a simple voltage divider circuit.
You’ll learn how a voltage divider works, how to assemble it using high-watt resistors and a precision potentiometer, and how to test it with a real AC high-voltage source.
This project is ideal for electronics students, technicians, and DIY enthusiasts who want to understand high-voltage measurement and build their own tools safely and affordably ⚡
