Resistors

There are many different types of resistors available. In order to identify or calculate the resistance value of a resistor, it is important to have

Resistors are used for many applications in a circuit. But all resistors are not suitable for all the applications. Resistors are selected using different parameters.

In Direct Current (DC), the flow of electric charge is unidirectional. In DC, the voltage and current maintain a constant polarity and direction. The source

Consider a task of moving a charge from A to B in a uniform electric field. Let this movement be against to the electric field.

Varistor is portmanteau of variable resistor. It is a passive non linear two terminal solid state semiconductor device. A Varistor, or Voltage Dependent Resistor (VDR),

Two resistors are said to be connected in parallel if both the terminals of a resistor are connected to each respective terminal of other resistor.

Resistors are the basic components of any electrical or electronic circuit. Often resistors are found in large numbers irrespective of the size of the circuit.

Resistors can be connected in series connection alone or in parallel connection alone. Some resistor circuits are made from combination of series and parallel networks

Like all electronic components, resistors are also available in different sizes, shapes and types. These variations make them to suitable to some particular applications only.

This article introduces resistors, essential components in electronic circuits, emphasizing their role in managing current flow and energy conversion, such as in light bulbs. It
