What is a high voltage item?
High voltage is actually a subjective term. An electric utility might define it as any voltage over 35000 volts. The 2005 National Electric code defined any voltage of 600 volts as high voltage. The highest voltage allowed in a residence is 240. The highest voltage found in most industrial plants is 480. A microwave oven can have several thousand volts and can be lethal. In 1994 a university professor at UTEP was killed by one. An old picture tube type TV can also have several thousand volts in its wiring. Neon lighting can have several hundred volts. Fluorescent light fixtures can have several hundred volts.
How many volts are there in a single A battery?
The old A batteries used in vacuum tube radios were initially 2 volts but later 1.4 volts became more common. You can find them also in other voltage ratings.
What would the voltage be in a DC circuit if there were a current flow of 6 A and a resistance of 8 ohms?
Ohms Law! E=IR Voltage equals current times resistance. Get out the old calculator...
What happen to voltage when a transformer is stepped up and stepped down?
A step up transformer increases the applied voltage. A step down transformer decreases or lowers the applied voltage. An example of step up transformers are the transformers (known as fly-backs) in old CRTs that stepped up voltage from 110 Volts to 25,000 volts. An example of step down transformers are the power bricks for laptops or any power adapter that step down the voltage from 110 volts to 12 volts, 9 volts or whatever is needed for your device. I must add that most (not all) power adapters also convert AC to DC.
How old was Alexander Fleming when he discovered panacilin?
Emily Scott LOVES Isaac Bryan Owens <3 <3 <3
How does a 350 Chevy engine temperature heat sensor work?
It is a resistor that changes resistance based on temperature 0 volts is cold 13 volts pins the gauge. The difference between the one wire and the three wire is the three wire is not Dependant on battery voltage. the old ones will read colder at 11 volts than at 13 volts
How many volts of electricity are in a phone line?
Phone lines operate at 48 volts when you pick the phone up to make a call and while talking, but 90 volts are sent to the phone you are calling to make the phone ring. This is a holdover from the old rotary phones that had the bells that were struck by a little hammer.
Does a power supply receive 120 volts?
The voltage your computer's power supply receives depends mainly on the standard electrical service delivered into homes, offices and factories by the national electrical grid in your country.Just a few examples: if you live in North America, that voltage is 120 volts but, if you live in, say, Europe or Australia, that voltage is 230 volts.More detailsThe voltages a power supply was designed to use depends on how old it is. Early power supplies were designed to use only one voltage: the standard voltage of the electrical service delivered by a country's national electrical grid for use by small appliances in homes, offices and factories .Since the invention of the personal computer most standard power supplies have been designed to operate on a wide range of voltages. (Such as from 100 volts to 250 volts.)
What happens to the brightness of a bulb if the volts are increased?
The electrical potential energy increases as the voltage is increased. It further excites the filament in the bulb more than a lessor voltage would. Using good old ohm's law (Voltage = Current x Resistance), a larger voltage applied to a bulb at the same resistance increases the current proportionally and larger currents has the effect to cause higher temps in conductors
Why does your car start then kill right a way after a couple sec?
It can depend on what kind of car you have, some cars have a voltage regulator that lets your distributor get 12 volts on start but then drops voltage on run. sometimes the run resist wire burns out, so you only get power to your distributor on the start circuit. The old type voltage regulator were porcelain with two wire resisters.
Who discovered laurasia?
Laurasia is an old continental mass that includes North America, Europe, and Asia. It was recognized after the proposal of Alexander Du Toit in his book Our Wandering Continents.
How old is Alexander Mejía?
As of June 2014, Alexander Mejía is 25 years old.
