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 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 ...
Resistors are electronic components that resist the flow of electrical current by dissipating its voltage in a manner called dropping. Simply put, a resistor will drop a percentage of a circuit’s voltage. That percentage is equal to the value of a given resistor, in ohms, when compared to t...
What is capacitor Capacitor is an electronic component that storeselectric 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 ...
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...
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...

Ohm's law says that in an electrical circuit, the current passing through a resistor between two points, is related to the voltage difference between the two points, and inversely related to the electrical resistance between the two points. This relation is shown in the following pee ...
Human beings are also good conductors of electricity, which is why touching someone experiencing an electric shock causes the toucher to experience the same shock. In electrical and electronic systems, conductors comprise solid metals molded into wires or etched ontoprinted circuit boards. ...
Normally when resistances are indicated on an electronic circuit diagram they are denoted as 10R for a ten ohm resistor, 10k for a ten thousand ohm resistor, and 10M for a ten MΩ resistor. The reason for this is that the Greek letter omega is not as easy to use as the prefixes R, ...
