Digital oscilloscopes tend to be more expensive than analogue ones, mainly due to a better accuracy with the digital versions. There are many places you can purchase oscilloscopes; including specialised shops, or even more general marketplaces such as Amazon and eBay. Prices range from ´£35 for a mini oscilloscope up to nearly ´£500 for a top-of-the-range one.

Very often in translations from German to English the term 'free wheeling diode' for 'Freilauf-Diode' is used. Generally the correct translation for this term would be 'recovery diode'. The usage of the term 'free wheeling' only will be correct in mechanical aspects, e.g. the rear wheel of a bicycle or the clutch of the transmission line of a car.

It depends on the Country, University and the Department you are apply to. Usually, Universities look at your Transcripts, GRE score, IELTS/TOEFL scores, Extra Curriculars, Research wok, Essays, Recommendations etc. for scholarship decisions.

The wattage must remain equal on the primary and secondary sides of a transformer. An example to the above statement with a 1000 watt step down transformer. To fine the watts (load) the formula is W = A x V. The primary side of the transformer has the capacity of 1000 W = 4.16 Amps x 240 Volts. The secondary side of the transformer has the capacity of 1000 W = 8.3 Amps x 120 Volts. Using the transformer to its maximum, without overloading it, the primary will be 4.16 amps at 240 volts and the secondary will be 8.33 at 120 volts. As you can see the wattage (load) remains constant only the voltages and current change.

• in bipolar transistors it is called the base
• in field effect transistors it is called the channel

A variable resistor usually has three terminals, one of which is connected to the 'wiper' by which means its resistance is measured.

By using all three terminals, we can control the potential difference in a circuit. When used in this way, we call the variable resistor a 'potentiometer'.

By using two of the three terminals, one of which must be connected to the variable wiper, we can control the current passing through circuit. When used in this way, we call the variable resistor a 'rheostat'.

silicon controlled rectifier is a 3 terminal 4 layer device which has 2 consecutive P N junctions here the three terminals called anode, cathode and gate gate controls the conduction of the scr but diode just conducts in forward bias and blocks in reverse bias

They do not get nearly as hot because they convert electricity to light much more efficiently. Most of the energy goes to light not hear. How this is done is pretty complicated though. Wikipedia LED if you want to know more.

The state machine described in the previous section is a deterministic finite automaton, in which each state is unique. What would make a finite automaton nondeterministic is if each state was not. For the example, if the state machine allowed the input to have any letter as the second letter for the word "person" to transition to the next, then the next state would not be unique, making it a nondeterministic finite automaton.

There is a way to use capacitors to increase the voltage in an ac circuit. It increases it by about 50 %. It was used to increase the voltage going to motors. It is seldom used now that it is much easier to run a higher voltage line into a place of business. It does not work for Direct Current.

the highest energy level which an electron can occupy the valance band at 0k is called fermi energy level

In an integrated circuit, electronic components such as resistors, capacitors, diodes, and transistors are formed directly onto the surface of a silicon crystal. The process of manufacturing an integrated circuit will make more sense if one first understands some of the basics of how these components are formed.

Even before the first IC was developed, it was known that common electronic components could be made from silicon. The question was how to make them, and the connecting circuits, from the same piece of silicon? The solution was to alter, the chemical composition of tiny areas on the silicon crystal surface by adding other chemicals, called dopants. Some dopants bond with the silicon to produce regions where the dopant atoms have one electron they can give up. These are called N regions. Other dopants bond with the silicon to produce regions where the dopant atoms have room to take one electron. These are called P regions. When a P region touches an N region, the boundary between them is referred to . This boundary is only 0.000004 inches (0.0001 cm) wide, but is crucial to the operation of integrated circuit components.

In a computer system, the motherboard holds all the other circuit boards. The video, sound, game ports, and all other daughter boards are attached to this important piece of hardware.

In order to decrease voltage without decreasing amperes you have to also decrease resistance.

Ohm's Law: Voltage = current times resistance

The purpose of 3 field crop rotation was to allow fields a chance to regain minerals in between periods of growing crops. Every time a crop is planted and harvested, minerals are lost from the soil. This is due to the plants taking them from the soil to aid their growth. To prevent the fields becoming infertile a 3 field crop rotation system can be used to help with this problem. By not using one field, or planting crops (such as clover) which return nutrients to the soil, it could maintain a good amount of crop produced each year without making the fields infertile.

The difference b/w the prime generator & standby generator is that the prime generator is used for 24/7/365, while the standby generators are only used in emergency cases, if we used standby generators for more than 24 hours continuously, then it will be overheated for sure.

Dr Gustave Bucky is the original inventor of the x-Ray grid. He made this in 1913. He was born September 3, 1880.

There are no volts in a toaster. Depending on your country of residence, your toaster may use 110v or 220v. Here's an easy way to tell.

If you are in Canada or the US, your toaster is the 110 variety.
If you are in Europe, Asia, the Middle East, and a few other countries, your toaster is the 220 variety.

an aeronautical engineer job is very sensitive and needs lot of safety minded conscious. it is a challenging profession in which you interact with master pilots and demands your involvement in such a way when ever snag occurs. you have to be technically sound and refer books all the time to keep your self in touch. since every activity is documented.it is called the life of aircraft. you are responsible for millions of rupees and precious lives.

The circuit has one inductor and capacitor connected in such a way that it produce the resonance condition for only one frequency. on the other hand for double tuned circuit it has more number of reactive elements and it has two tuning frequency. The single tuned circuit is of interest when the poles are imaginary, and rest of the two cases are not more interest. w=wn the time it produce the resonance and the damping factor zeta is zero and the circuit is in undamped condition.
