Potentiometer: How it Works?
What is Potentiometer? Potentiometer or Rheostat is one type of passive variable resistor (variable potentiometer) either carbon or wire wound, with three terminals used to get the desired voltage division. Hence, the name variable voltage […]
How to Measure Resistance
How is the Resistance Measured? To measure an electrical resistance (Low resistance, Medium resistance, and High resistance) electronic instruments use two measurement techniques. They are constant voltage and constant current. The constant voltage method measures […]
Power rating of Resistors and Wattage
The Power rating of a resistor can be said as the maximum amount of power that the resistor can withstand. The resistor power rating is the specification given to a resistor other than the ohms […]
