But, the really difficult inventions are the physical and chemical ones. They mean bigger risks. They may be losing out because hardware is hard. It's much harder to scale up a physical or chemical invention than it is a software based invention. Think of batteries. Lithium-ion batteries in...
How do charges move through a circuit?The Flow of ElectricityAlessandro Volta was the first to discover that bathing two different metals in a salt water solution allows him to create an electric current. Connecting these wet cells together in series gave him relatively large quantities of ...
Let's find out. Circuit Breaker: At Work in Your Home This diagram shows the basic parts and design of a circuit breaker. HowStuffWorks The power distribution grid delivers electricity from a power plant to your house. Inside your house, the electric charge moves in a large circuit, ...
If you're wondering how to reset a breaker, you've come to the right place. Not only will we explain how to reset a breaker in this article, but we'll also discuss how to deal with circuit breaker trips and an overloaded circuit. Better yet, we'll make sure you take proper safety...
PCB here means (Printed Circuit Board) and it's possible a power surge can damage it. This has nothing to do with physical damage to the drive but its effects can be quite extensive because PCB, by default, connects electronic components; when it's damaged, you can be sure other parts ...
When switches are closed, there is no gap in the circuit, so electric charge can flow. This means that the circuit will work, and the bulb will light up. So, the bulb in circuit B will light up. Switches allow us to turn things on and off, but why is this useful?
Instead they have a characteristic such that large overloads (e.g., due to a short circuit, potentially drawing hundreds or thousands of amps from the distribution transformer) will cause the fuse to blow in fractions of a second, whereas small over currents could take minutes to blow the ...
Connecting transistors in parallel is a process in which the identical pinouts of two or more transistors are connected together in a circuit in order to multiply the power handling capacity of the combined parallel transistor set. In this post I have explained how to safely connect multiple trans...
If you want to get a really good understanding of capacitors and how to use them in your circuits, there are two important things you need to know: What happens to thevoltage across the capacitorwhen you charge it? What happens to thecurrent through the capacitorwhen you charge it?
comparable to the typical self-discharge rate of the battery cells. The circuit operates from a supply voltage as low as 1.7V and requires less than 2µA of supply current. This ensures that, even for a battery with a minimal remaining charge, the circuit still...
