In the next section, we'll look at some of the alarm types you might find in a typical security system. Sounding the Alarm There are several things a security system might do when it detects an intruder. In an advanced system, the control box will be wired to several different ...
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, ...
In this article, we'll try to provide a less slippery answer. We'll illuminate just what electricity is, where it comes from and how humans bend it to their will. For our first stop, we'll travel to Greece, where inquisitive ancients puzzled over the same phenomena that zaps you when ...
The bonding method ultrasonically bonds the plurality of strands of the electric wire (1) to each other using an anvil and a horn. When the strands are ultrasonically bonded to each other by clamping a part of the conductor (3) exposed from the sheath (5) between the anvil and the horn...
Without involving devices in the transit of electricity, or those used in its production and adaptation, the way the wires work is really very simple. The core of conductive metal, most often copper though aluminum has been used in the past, is attached to a source of electricity. This coul...
Before removing wire from a push-in receptacle, be sure to shut off power to the circuit as a safety precaution; then double-check using a tester. You'll need to remove the electrical outlet from the wall, taking care to note how the wiring is connected.
As the turbine turns, the excitor sends an electrical current to the rotor. The rotor is a series of large electromagnets that spins inside a tightly-wound coil of copper wire, called the stator. The magnetic field between the coil and the magnets creates an electric current. In the Hoover...
Power surges occur when something boosts the electrical charge at some point in the power lines. This causes an increase in the electrical potential energy, which can increase the current flowing to your wall outlet. Several different things can cause this to happen. The most familiar source is...
Nearly all of our cellshave the ability to generate electricity. And in this article, we'll look at the role of electricity in the human body and find out how we produce it in the first place. The starting point is simple: Right now, any cells in your body that aren't actively sendi...
wires. So hot wires send electricity from the power source to your appliance (or load), and neutral wires return the electricity back to the power source (if the current is imbalanced between the two hot wires). But what happens if there is an unexpected flow of electricity in the circuit...
