Mindblown: a blog about philosophy.

 In North America, we find another device called a GFCI or a ground fault circuit interrupter. In Europe, this is called an RCD or residual current device. These basically monitor and compare the current in the supply and return wires to a circuit. If the current coming back is not equal to the current being…

With the overload function, if we slowly add more load to the circuit, we will eventually exceed the rating of the breaker and it will flip to cut the power and protect the circuit. This is known as overload protection. Another feature of most modern circuit breakers is short circuit protection. In this case, if…

 We find circuit breakers in our electrical panels within our homes and places of work, circuit breakers are essentially a switch that automatically opens to break the circuit if too many electrons pass through it in either an overload or a short circuit scenario.

Fuses, in a basic sense, have a thin piece of wire inside them, which is rated to handle a certain amount of current flowing through them. In this case, this one is rated to handle three amps or 19 quintillion 272 quadrillion electrons per second. If too much current flows in the circuit, then the…

Resistors make it harder for electrons to flow through a circuit, and that’s why we add resistors to the circuits because they reduce the current, it’s like having a kink in a pipe. This will add resistance to the flow of water, which reduces how much water can flow through. And as the water is…

 If you look on the plugs of your electrical devices, you should find labels from the manufacturers which tell you what the product is designed to handle. For example, this laptop charger tells us that for the device to work, it needs an input of between 100 and 240 volts and 1.5 amps of AC…

Something that’s going to cause you great confusion when you’re learning about electricity is the difference between conventional current and electron flow. These are both theories of how electricity works. When Benjamin Franklin was first experimenting with electricity, he had the idea that something must be flowing inside the materials, he was given a glass…

Learn about electrical current to understand the different types, the symbols used to represent them, how to measure current and how safety devices are used to protect us and our electrical circuits. What is Current?  Current is the flow of electrons in a circuit. To use electricity, we need electrons to flow in the same…
