Soft soldering is a technique used to join wires, fix electronic components onto circuit boards and bond copper pipes together. This tutorial shows you how to solder step by step.
A tutorial which shows the derivation of formulas for resistors connected in series and parallel.
The simple RC circuit is a basic system in electronics. This tutorial examines the transient analysis of the circuit as it charges and discharges in response to a step voltage input, explaining the voltage and current waveforms and deriving the solution of the differential equations for the system.
A current transformer is an instrument transformer, used along with measuring or protective devices, in which the secondary current is proportional to the primary current (under normal conditions of operation) and differs from it by an angle which is approximately zero.
We've all experienced short-term, local power outages, but what kind of problems would we have if the power was out for a week, or even longer? What if the blackout was widespread? We depend on electricity for more than lights and TV. We will be in big trouble if the power grid goes down for long.
Have you have considered the power potential of the human body? What about the energy stored in a raindrop? In this article I discuss five strange methods that could one day become an integral way that civilization generates electricity.
This article covers everything you need to know about electrical power.
