  Understanding NTC and PTC Thermistors: A Guide to Temperature-Sensitive Resistors In the world of electronics, temperature sensing and control are critical in many applications—from home appliances to industrial equipment. Among the most commonly used temperature sensors are thermistors , specifically NTC (Negative Temperature Coefficient) and PTC (Positive Temperature Coefficient) types. Let’s explore what they are, how they work, and where they are used. 🔍 What is a Thermistor? A thermistor (short for “thermal resistor”) is a type of resistor whose resistance changes significantly with temperature. Unlike standard resistors that maintain a fixed resistance, thermistors are highly sensitive to temperature variations. There are two main types: NTC Thermistor – Resistance decreases as temperature increases. PTC Thermistor – Resistance increases as temperature increases. 🌡️ NTC Thermistor (Negative Temperature Coefficient) How It Works: In an NTC thermisto...

 register is an electrical component used to reduce the electrical current in a circuit. The register is measured in units of ohms and has two terminals.  The register is constructed using carbon or metal wire. There are mainly two types of registers, fixed value registers, variable registers.  Fixed value resistors,  The value of fixed value register is always fixed, its value cannot be increased or decreased whereas the value of variable register can be increased or decreased.  Resistor Color Code Calculator Resistor Color Code Calculator Select the colors of the bands on your resistor: Band 1: Black Brown Red Yellow Green Blue Violet Grey White Band 2: Black Brown Red Oregon Yellow Green Blue Violet Grey Whi...

  Diode  Diode is an electrical component. Its full name is Semiconductor Diode Valve. The diode was discovered in the 19th century by a scientist named Thomas Edison.  Diodes are made of germanic silicon semiconductor. There are many types of diodes, but most of them have two ends, one anode and the other cathode.  Speciality  The main feature of diodes is that they allow current to flow in only one direction with low resistance. While they do not allow the electric current to flow in the opposite direction, due to this feature, they convert AC (alternating current) to DC (direct current).  Main work  Diode is the most commonly used electrical component. Diodes are mainly used to convert AC current into DC current. Apart from this, diodes are used in battery chargers, inverters and all electrical equipment running on DC current. Symbol  The diagram below shows the symbol used in the c...
