Ohm's Law
The relationship between Voltage, Current and Resistance in any DC electrical circuit was firstly discovered by the German physicist Georg Ohm. Ohm found that, at a constant temperature, the electrical current flowing through a fixed linear resistance is directly proportional to the voltage applied across it, and also inversely proportional to the resistance. This relationship between the Voltage, Current and Resistance forms the bases of Ohms Law and is shown below.

Electrical Safety Tips
With great power comes great responsibility. No, no, I’m not talking about Mr. Peter Parker. I’m talking about electricity, one of the most convenient and useful items in homes today. In fact, I bet you’re using electricity right now! Whether you’re charging your laptop, watching TV, or just using a lamp, you’re making use of the wondrous wonder that is electricity. But with electricity’s power comes a great potential for harm. If you don’t use electricity properly, you’re liable to end up shocked, aflame, or worse.
Georg Simon Ohm und der elektrische Widerstand
Georg Simon Ohm erkannte den Zusammenhang zwischen Stromstärke, Spannung und Widerstand. Mit dem Ohmschen Gesetz legte er den Grundstein für Telegraphie, Elektronik und Mikroelektronik.
What is Electricity ?
Electricity is a natural phenomenon that occurs throughout nature and takes many different forms. In this tutorial we’ll focus on current electricity: the stuff that powers our electronic gadgets. Our goal is to understand how electricity flows from a power source through wires, lighting up LEDs, spinning motors, and powering our communication devices.
4 Ways To Save Electricity
For many people, electricity is still quite mysterious and the concept of saving electricity is quite abstract. For example, we all know that we should turn lights off when we leave a room to save electricity but this is at odd with how we feel. Having a bright room makes us feel safer, warmer and happier, even if we are wasting electricity. Even if you don’t know your amps from your volts, here are four tips that will help you save electricity effortlessly.
