Who does electrical work?
Electricians are trained to work in the electrical trade. Linemen are trained to work on the primary high voltage side of the electrical trade.
Why does heating element get hot when current flows?
The current is doing work against the resistance of the material which makes up the heating element.Because it has resistance.-- Whenever electric current flows through a resistance, it loses energyequal to (current-squared) x (resistance).-- When we connect components in an electrical circuit, we use wire withthe least possible resistance, so as not to lose energy in the wiring.-- When we want to warm up the lab, we use wire with significant resistance,in order to have it dissipate significant energy and radiate heat.
Is resistance to antibiotics permanent?
No, resistance to antibiotics is not permanent. However, once you have a resistance, that antibiotic will no longer work for specific infections.
What items are used to complete a circuit?
A source of electrical potential difference or voltage. (typically a battery or electrical outlet)A conductive path which would allow for the movement of charges. (typically made of wire)An electrical resistance (resistor) which is loosely defined as any object that uses electricity to do work. (a light bulb, electric motor, heating element, speaker, etc
How do compression load cells work?
Compression load cells work by measuring the force or load applied to them through compression. They contain a strain gauge sensor that detects changes in electrical resistance caused by the slight deformation of the load cell when subjected to pressure. This change in resistance is then converted into an electrical signal that can be calibrated and used to determine the applied load.
What material has no electrical resistance?
A superconductor. So far, it has only been possible to produce superconductors that work at extremely cold temperatures.
What is current voltage power and resistance?
current - movement of electrical chargesvoltage - electrical force/pressurepower - work doneresistance - opposition to currentinductive reactance - opposition to changes in currentcapacitive reactance - opposition to changes in voltagetotal impedance - vector sum of resistance, inductive reactance, and capacitive reactanceetc.
What is resistance when lifting weight?
Resistance is the amount of contrary force against which your muscles must work in order to complete a movement. Most often, these are the weights being lifted or resistance bands being stretched.
Why car battery terminal heats up?
It's called resistance. Every electrical circuit has resistance to the "flow" of energy. This is how electric heaters work. Take a small diameter piece of wire, and put a lot of electrical current through it. The thinner the wire, the more it will heat up. If the wire is too thin, it will burn and break. This is why you want an adequate "gauge" of wire for your electrical needs.
When you do resistance exercise you work against what resistance?
Weight

How do you work out amps in an electrical circuit?
Current symbol I =voltage/resesistance I=V/R for direct current (dc) and for a resistive load in alternating current (ac)
What type of drama represented the impressionism period?
One work that is often associated with this period is Maurice Maeterlinck's work Pelléas et Mélisande, which was later the basis of an opera by Claude Debussy.

When the front gas tank is unhook out of a ford 150 how could the gas meter still be reading full?
Gas gauges work based on electrical resistance. When the float in the tank is moved up or down by the fuel level, it changes the resistance and the gauge reads differently. Some gauges read full if resistance is high and full is resistance is low. If I understood the question, you unhooked the gauge and it is reading full, that is because you have opened the electrical contacts to unlimited resistance. But, if the gauge was always reading full, before you disconnected it, and that was the root of your problem, then the wire could be shorted to chassis ground and the gauge is reading the resistance of the entire truck.
How does the resistors work in a integrated circuit?
A resistor implements electrical resistance as a circuit element. It works in an integrated circuit by reducing current flow, and to lower voltage levels within circuits.
How do car amps work?
Hi, Amps are electrical and the same in a car as elswhere. Amps are a quantity of electricity, voltage is the pressure pushing it and resistance is, as it sounds, how difficult it is to push it. Peace, crigby
