Make the light bulb light up with the battery by touching the bottom tip of the bulb to the positive or bumpy end of the battery. The bulb contains two wires extending into the inside of its base that create the circuit that lights the bulb. One stops at the side of the metal base a...
When voltage is below a certain level, the electrons in the semiconductors flow in such a way as to create a very high resistance. When the voltage exceeds that level, the electrons behave differently, creating a much lower resistance. When the voltage is correct, an MOV does nothing. When...
So an LC resonant circuit is able to output sine waves. Thus, LC resonant circuits are used many times to create sine wave signal generators. In this circuit, actually, we will build the simplest LC resonant circuit that can be built. We will input a square wave signal into the LC reson...
If you need to have your meter changed, moved, or adjusted, you must work with your utility to get that work done. How Does an Electric Meter Work? You’ve probably stared at the spinning numbers on a power meter and wondered, "What does an electric meter do, and how does it calcula...
Here, an electromagnet is used to pick up some of the approximately 3,500 confiscated guns to be melted down. David McNew/Getty Images What do a wrecking yard, a rock concert and your front door have in common? They each use electromagnets, devices that create a magnetic field through ...
A circuit breaker is an incredibly simple tool used to control the flow of power to a household or business. Construction Photography/Avalon/Getty Images The circuit breaker is an essential device in the modern world and one of the most important safety mechanisms in your home. Whenever ...
Each one came in a little metal can about the size of a pea with three wires attached to it. It might take three or four transistors and several resistors and diodes to create a gate. In the early 1960s, integrated circuits (ICs) were invented. Transistors, resistors and diodes could ...
An array of sensors that can include switches, pressure sensors and motion detectors (a problem with any of these sensors could cause your alarm to go off when it doesn't need to) A siren, often able to create a variety of sounds so that you can pick a distinct sound for your car A...
The water in this reservoir flows through the hydropower plant to create electricity. Lower reservoir - Water exiting the hydropower plant flows into a lower reservoir rather than re-entering the river and flowing downstream. Using a reversible turbine, the plant can pump water back to the upper...
The circuit you create should energize the regulator when you plug it into the circuit. Three-terminal alternator setups usually mean you have to use an external regulator to connect the alternator to the regulator and connect the regulator to the battery itself. After you have the circuit set...
