A resistor (also known as an electrical resistor) is defined as a two-terminalpassive electrical elementthat provideselectrical resistanceto current flow. Resistance is a measure of the opposition to the flow of current in a resistor. The larger a resistor’s resistance, the greater the barrier ...

A Resistor is an electrical device that resists the flow ofelectrical current. It is a passive device used to control, or impede the flow of, electric current in an electric circuit by providing resistance, thereby developing a drop in voltage across the device. We need some way to control...
The resistor is a component that resists the flow of current. It doesn’t do anything actively, so it’s called apassivecomponent. Sounds boring and pretty useless, but it’s actually an extremely useful component. Once you know the basics of the resistor – and how it works with currents...
The resistor is one of the most important components in an electronic circuit as it allows the designer to precisely control the amount of current and voltage flowing at certain areas in the circuit. Therefore, it is an absolute requirement to ensure that sensitive electronic components such as ...
Chapter 1 - Resistor Fundamentals The resistor is a passive electrical component that creates resistance in the flow of electric current. In almost all electrical networks and electronic circuits they can be found. The resistance is measured in ohms (Ω). An ohm is the resistance that occurs whe...

LDR (Light Dependent Resistor) as the name states is a special type of resistor that works on the photoconductivity principle means that resistance changes according to the intensity of light. Its resistance decreases with an increase in the intensity of light. It is often used as a light senso...
Working Principle of Resistor A resistor collects electrical energy while restricting current flow and lowering voltage, which it then must release as heat. The heat transfer in the majority of contemporary electronic circuits is generally less than 1µW. ...
Capacitor is an electronic component that stores electric charge. The capacitor is made of 2 close conductors (usually plates) that are separated by a dielectric material. The plates accumulate electric charge when connected to power source. One plate accumulates positive charge and the other plate ...
