Ohms Law - Amps Volts Watts Relation

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.

Ohms Law

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.

Ohm's Law - Watlow Electric The one i used to use, This would be in the back of the handbook.

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..

    Genrad - General Radio - Instrumentation

    History and accomplishments of the General Radio Company, one of America’s first equipment manufacturers for the radio and electronics industry.

    General Radio Historical Society

    Founded in Cambridge, Massachusetts in 1915, GR provided the tools and instruments that allowed the electronics industry to burgeon into today’s giant that fills our lives with radio, TV, computers, cell phones, DVDs and all the other electronic products in our homes, businesses and automobiles.

    GenRad 1863 Megohmmeter

    The GenRad 1863 Megohmmeter is the choice for production and inspection tests on devices with resistances up to 20 Tohms. The GenRad 1863 will measure resistance at any of five test voltages of: 50V, 100V, 200V, 250V, and 500 VDC. Compared to the GenRad 1864, which has adjustable test voltages from 10V to 1090V, this unit has fewer controls, and is the more economical of the two models. - GenRad 1863

    Electrical Safety and Clean Energy Systems

    This is an educative and important guide for Electrical Equipment Safety. This can be also applied partially to Power Electronics and Home Energy Systems. Electronic Equipment also have to be maintained by Calibrating them and protecting them from environmental parameters like dust, grime, direct sunlight, moisture, humidity, sea wind (brine), corrosive fumes and chemicals. They should not be even placed near machines like a big lathe, sub-sonic or low frequency vibrations.

    Electrical Safety is a Serious Issue Electrical Safety in the workplace is the most important job of an electrical worker. No matter how much training one has received or how much employers try to safeguard their workers, Electrical Safety is ultimately the responsibility of the electrical worker.

    Earthing or Grounding is something Audio Enthusiasts make a lot of fuss about. The Articles here about Balanced Power, Symmetrical Power Systems and Earthing throw light on ways to counter Audio Noise.

    AC Power has the 50/60 Hz noise, now more AC noise can be picked up by poorly designed systems when so many gadgets around. These articles are also relevant for the instrumentation engineer. Dissonance is encountered when you build sensitive strain gauge based measurements or while measuring and transmitting micro-volts from a remote sensor to the dashboard/control panel.
