There is a very dangerous myth floating around, one which could actually result in severe injury and even death – “Electricity always follows the path of least resistance”. This is one of those myths that results from a general fact being blown way out of proportion.

Forget colleges and engineering schools, most high school students learn that electricity does behave this way, as a part of the basics of electricity and resistances. Worryingly, this myth isn’t just stated as a fact, it’s a commonly followed practice in many electrical circuit designs, especially when it comes to grounding.

Walk into any industrial plant that uses motors or pumps and you’ll find they’re all connected to ground rods. Ask anyone why that’s done and you’ll likely get the same response everywhere (even from the people in charge of the electrical maintenance) – It’s to eliminate the potential differences.

Ceiling fans are sometimes looked over when decorating a home. Besides of freshening a room, fans complete a room design and composition. It’s important to understand how size and height affect the fan’s efficiency and overall look of a room. A ceiling fan that’s too big will overpower the room’s design and visually pull the ceiling downwards; a fan that’s too small won’t properly circulate the air.
