What is an NTC Thermistor? | Working, Formula & Real Uses | Demystifying NTC Thermistor
In this video, we explore the working principle of the NTC (Negative Temperature Coefficient) thermistor in the simplest way possible. Learn how resistance changes with temperature, why NTCs are used in SMPS power supplies, battery packs, chargers, LED TVs, and how they protect circuits from high inrush current during startup.
We will understand:
What an NTC thermistor is
How NTC works internally
Why resistance decreases when temperature increases
NTC used as temperature sensor
NTC inrush current limiter working
Difference between NTC and PTC
Real circuit examples from SMPS and electronics
Testing NTC using a multimeter
This video uses simple explanations, circuit diagrams, waveform visualization, and real-world examples so beginners can easily understand the concept.
Perfect for:
Electronics beginners
Engineering students
Repair technicians
SMPS learners
DIY electronics enthusiasts
