Circuits

The first patent for the field-effect transistor principle was filed in Canada by Austrian-Hungarian physicist Julius Edgar Lilienfeld on October 22, 1925, but Lilienfeld did not publish any research articles about his devices. In 1934 German physicist Dr. Oskar Heil patented another field-effect transistor. There is no direct evidence that these devices were built, but later work in the 1990s shows that one of Lilienfeld's designs worked as described and gave substantial gain. Legal papers from the Bell Labs patent show that Shockley and Pearson had built operational versions from Lilienfeld's patents, yet they never referenced this work in any of their later research papers or historical articles. On 17 November 1947 John Bardeen and Walter Brattain observed that when electrical contacts were applied to a crystal of germanium, the output power was larger than the input. William Shockley saw the potential in this and worked over the next few months greatly expanding the knowledge of semiconductors and is considered by many to be the 'father' of the transistor.

1956 John Bardeen, Walter H. Brattain and William Shockley received the Nobel Prize in Physics for inventing the first silicon based transistor

Voltage doesn't harm you. Current does. If you can sufficiently reduce the resistance

at the points where the power supply connects to your body, you can do yourself

a lot of harm with a very small voltage.

I am an electrical engineer. We were discussing this exact question in the engineering

dorm, on a night more than 50 years ago that I can never forget. A debate got going

over whether it's possible to kill someone with 12 volts. Some said yes, some said no.

A very stupid proof of concept was proposed, and played out to its unfortunate

conclusion. A method of low-resistance connection was proposed, and one of those

who said it couldn't be done bravely demanded to be the one to demonstrate it,

and show everyone else that it couldn't be done. The power source selected was

a 12-volt car battery, the means of connection are better left not described, and

for the rest of the night, each of us in the group was interviewed privately, one

at a time, by the police, after his body was removed from the dorm.

So I'll say: less than 12 volts, if you know how to do it.

ratio between true power and apparent power is called the power factor for a circuit

Power factor =true power/apparent power

also we conclude PF=power dissipated / actual power in pure resistive circuit

if total resistance is made zero power factor will be zero

There is many uses for the resistor in electronic circuits, like current limiting, voltage division, R/C oscillators and many more.

Without the resistor electronics is not possible

power demand will increase in generating stations

tariff will go up

savings of energy for future is very important

Depending on what type of circuit your talking about.If the circuit is in parallel,series/parallel,then your talking as many loads that there are on the circuit.However if your dealing with the basic series,then there are the going out and coming back in. so two.and that's not including the ground path.

ANSWER :Only one path and there is from a positive to a less positive potential

A circuit breaker limits the amps that a circuit can carry. If the amperage draw on a circuit exceeds that limit, the circuit breaker turns off the circuit.

If the current through a wire exceeds the rated amperage, the wire will overheat and eventually cause a fire, or at a minimum, destroy the wire behind inside the wall.

Obviously, people don't want a house fire caused by an electrical overload, so circuit breakers are used to prevent damage and potential loss of life.

The name for this is a brown-out.

It is the path of the electric current through the body that will kill, not exactly the voltage. If the electricity go through the heart, it will have a higher chance of killing that person. Generally 100-300 voltage can shock the heart to defrillation. Higher voltage will probably stop the heart, and the heart could be burnt from the high voltage too. If the body is NOT earthed, the body could probably survive.

1944 Construction on it started in 1943 and it was unveiled in 1946. Hope this helps!

The two basic types of circuits are series and parallel circuits.

date and time is one of them it also stores settings about drivers on the computer

Mainly overwhelming reduction in computer size, phenomenal increase in computer speed, reduced power consumption, reduced heat dissipation and an astonishing increase in overall computing power. Other than that, there haven't been many advantages to integrated circuits.

The four elements of a complete (electrical) circuit: 1)A source of input (power supply) 2)A means of conductivity (usually wire) 3)A means by which to open and close the circuit (a switch) 4)An output device (motor, light bulb, etc)

magnitude comparator is a logic circuit used to compare the two binary numbers in order to determine the relationship between those quantities.

Usually you should use an alcoholic wipe (try your first aid kit), but a baby/wet wipe and kitchen role to dry would work.

It is called the loopdie loop circut.

-- proliferation of electrical and electronic devices in the home, leading to a

surprising and shocking bill at the end of the month;

-- excessive current flowing in an inadequately sized conductor, leading to

overheating and possible fire;

-- grave mortal danger to a human person, caused by placing his body in-circuit

between the mains supply and a grounded point.

Note that none of these risks is "caused by" the mains voltage. Any risk is due

to careless and inattentive handling of the mains supply by people responsible

for its proper use. In this respect, mains voltage is no more risky than a car,

a bottle of sleep aid tablets, a pistol, or a discarded banana peel.

It stores electrical energy charge which then provides power to the circuit. Electricity is the stream of electrons through a conductive way like a wire. This way is known as a circuit.

Batteries have three sections, an anode (- ), a cathode (+), and the electrolyte. The cathode and anode (the positive and negative sides at either end of a conventional battery) are snared to an electrical circuit.

Yes, very easily. Copper is an excellent electrical conductor.
