Resistors are one of the most crucial components in any electronic circuit. From providing power to preventingshort circuits, resistors are an integral part of every power supply and build with the electronics you use on a daily basis. TheFixed Resistoralso known as “linear” or “ohmic” resi...
A reference stage includes a first transistor, a second transistor and a resistor that are connected in series from a voltage rail to a reference load. The resistor has (i) a resistance that is a function of a digital resistance-controlling value, (ii) a first terminal coupled to a gate ...

Somewhere in a circuit is a resistor. A constant current is flowing in the direction as indicated in the following figure. In going from A to B, we measure un
The most widely used type of resistor is the fixed resistor. They are used in electronics circuits to set the conditions for a circuit. During the design phase their values are determined, which from then on. they should never need to be changed to "adjust" the circuit. ...
Resistors are useful to reduce the voltage passing across a circuit. It is a rather straightforward gadget. The middle of a resistor constructs with a substance, such as carbon, that only partially conducts electricity. The resistor’s primary function is to lower the current’s voltage. The ...
