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
