The most important Electrical Law is the Ohms Law, a proper understanding of which can help you make many designs. Troubleshooting Home Appliances or understanding Household Wiring is easy if you master this.

Volts is analogous to the pressure of a water in an Overhead Tank. The water head or height is like Voltage. The Pipe diameter and bends are like wire and its resistance, a water tap like a wirewound potentiometer. The rate of water flowing from the tap is like the flow of electric current in a wire.

The water drops are similar to units of charge, the quantity of water filled in a bucket is like the amount of charge stored in a small capacitor. The Underground Sump can be compared to a Big capacitor. The evaporation of water is like leakage of charge thru the dielectric in a cap. If you use the running water to power a home made paddle wheel turbine; This is like simulating an electric motor or heater in a water circuit, the rotary power got, can be analogous to the heater’s watts..

Since its founding in 1988, Circuit Cellar has delivered exactly what its paying subscribers demand-intensive, exploratory articles about hardware and software methods for embedded-control systems.

Circuit Cellar - The Magazine for Computer Applications

Are you wondering how it all began?
By Steve Ciarcia (Founder, Circuit Cellar)

“His first statement upon hearing about BYTE’s redirection was “How about we start our own magazine?” We had the staff, the expertise, the credibility, the support, and most importantly, the money. It was time to go for it.

“A little bit of everything for makers, crafters, and budding scientists, from Arduinos to sock monkeys to chemistry sets .”

The 3D Christmas Tree Kits are a great way to celebrate the season – simply solder the LEDs and attach the PCBs to form a 3-dimensional Christmas tree that will brighten any desk or cubical. 9V battery and soldering required. Create some holiday cheer.

Solder: Time Watch Kits are an easy to solder real time watch kit with a unique laser cut acrylic casing. Four individual acrylic parts are cut to fit the internal PCB, battery and switch perfectly. Includes a velcro wrist band. After soldering the Solder:Time,

The Tiny Cylon kit is fun and easy to solder multi-mode LED Larson scanner kit. It features 5 red LEDs that blink or glow in various patterns. The Tiny Cylon uses an Atmel ATtiny 13 for is brains that comes pre-programmed with multiple LED sequences.

He was an American Mathematician and Electrical Engineer. He fostered the development of alternating current that made possible the expansion of the electric power industry in the United States, formulating mathematical theories for engineers.

(April 9, 1865 – October 26, 1923)

Charles Proteus Steinmetz

He made ground-breaking discoveries in the understanding of hysteresis that enabled engineers to better design electric motors for use in industry.
