The conductance is a property of a substance due to which it facilitates the flow of current through it when a voltage is applied across the substance. It is the opposite property of resistance. Because …
When a number of resistances are connected in head to tail manner one after another in series is called resistances connected in series or simply resistances in series. We sometimes also call it series resistances. The equivalent resistance of a series combination of resistances is algebraic sum of all the …
In the parallel combination of resistances, we connect more than one resistance. here, we connect more than one resistor in a certain manner. We connect one end of all the resistors to a common node. …

There are different types of resistors. An electrical circuit is incomplete without a resistor. A resistor is a passive component. The component that cannot amplify or process an electrical signal is a passive component. Resistors …
To identify and select a resistor by its value resistor color coding is necessary. We find resistors in many applications in electrical, electronic and communication industries. Because resistors play a significant role in producing voltages …
