How Resistors Work: Understanding the Fundamentals of Resistance
Resistors have a wonderfully practical name - they literally resist the flow of electrons. In previous tutorials and videos, we talked about the nature of electricity and the way that electrons want to spread out and be as far apart from each other as possible.That desire for the electrons to be somewhere with less electron density is voltage and, without resistance, …
Capacitor in Electronics – What It Is and What It Does
A capacitor is an electrical component that stores energy in an electric field. It is a passive device that consists of two conductors separated by an insulating material known as a dielectric. When a voltage is applied across the conductors, an electric field develops across the dielectric, causing positive and negative charges to accumulate on the conductors.
What is reactive Power and how it is generated and what is its …
Real power is energy that has been consumed by the load. It has been converted into another energy form and isn''t coming back. Reactive power is simply energy that is being stored in the load by any capacitors or inductors inside it. It can be returned to the source and indeed does so on a cycle-by-cycle basis in linear AC systems.

$begingroup$ Alas time marches on, and there''s very little difference now between the price of 5% tolerance carbon film and 1% tolerance metal film resistors. E12 was specified for ±10% tolerance in the early 60s (based on existing preferred values going back to the early 50s). E96, believe it or not, is specified for ±1%, though E48-E192 don''t line up with E3-E24.

2.8 Power and energy in resistive circuits We now consider the power and energy absorbed by resistors and supplied by sources in more detail. Recall that a voltage drop (a decrease in electric potential) across a circuit element in the direction of positive current flow represents energy absorbed. This is the case when current moves through a resistor.
