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 […]

Coulombs Law

Coulomb’s law definition in physics is explained by the concept of electric charge and electric force. According to Electricity, moving electric charges experience force when kept in a magnetic field. Here the charge is in […]

Electric charge

What is Electric Charge in Physics? In physics, Electric charge is the physical property of matter that causes it to experience a force when placed in an electromagnetic field. An electromagnetic field is a physical […]

Resistors in Series Connection

When a number of resistors are connected in such a way that the end of first resistor is connected to beginning of second resistor and the end of second one to third resistor and so […]

Resistor Color Code

Resistor color code indicates that a series of colored bands are painted on the resistor and most of the manufacturers identify their resistance value by means of a color code. There are various values of […]

Temperature Coefficient of Resistance

Temperature coefficient of resistance, this is the factor that temperature does affect the value of resistance in a resistor or a conducting wire. All the resistors value of resistance is specified at specific temperature and […]

Voltage Divider and Current Divider

Voltage Divider and Current Divider are the most common rules applied in practical electronics. As you know, there are two types of combinations in a circuit, they are series and parallel connections. Parallel circuits are […]
