Why silicon diode require 0.7v drop across it before it start conducting?

A: Actually it begins to conduct almost as soon as there available current. but the current is such a low value that it is considered not to be conducting at all. And the 0.7 volts drop is a chosen value to indicate that the diode is fully conducting and the voltage drop across is .7 volts there about. It can have any value lower then that and it all depends on the current flowing at the time.

What allowed computer technology to develop?
THE SILICON CHIP -The term silicon is important in the computer industry. Microchips that let computers work are made from silicon. Scientists developed the first trial silicon chip in 1958. Before that time computers were made of transistors. In 1958 scientists thought that silicon microchips were impressive because each chip could hold more than 30 transistors. Today's silicon chips often have more than a million transistors. Silicon microchips have helped make modern computer technology possible.
What temperature does a standard CPU melt?
CPUs are made of silicon, which melts at about 1400 degrees centigrade. However, other components of the CPU would be damaged long before the chip reached this temperature.
Why don't we use germanium as a control device in silicon control rectifier?
Generally SCR is used at high power applications, in order to withstand the temperature dissipated in the SCR, THERMAL STABILITY is very high enough. It means that thermal stability of silicon is very high compared to germanium that's why germanium is not preferred. But that does not mean it is not possible, in fact before silicon became common in the 1960s devices equivalent to the SCR were built using germanium!
What the advantages of the Golden Gate Bridge?
Before the Golden Gate Bridge was built, the only way across the Golden Gate was the Golden Gate Ferry System. After the bridge was built, automobiles could get straight across, rather than go around.
Silicon uses in electronics?
Silicon is used in electronics as a semi-conductor. All of the processing units in computers now use silicon to keep parts from causing electrical signals from passing from part to part unless it is meant to. Silicon is also used in the making of transistors.
Is silicon more reactive than sulfur?
Because Aluminum comes before Silicon in the dictionary
What are silicon chips replaced of?
Silicon chips replaced individual transistors and before that vacuum tubes (valves).
Does silicon need to be processed before it is used?
yes it needs to be processed before it is used

Can you transport a body from tn to mi?
Yes, but most state laws require a body to be embalmed before it can be transported across state lines and be done by properly licensed people or organizations.
What are the qualifications one needs to become a locksmith?
The qualification needed to become a locksmith vary greatly from state to state across the US. Some of the states require some kind of apprenticeship under a licensed locksmith, before giving a license. Some states require one to take an exam before being given a license.
What does a scientist need to review before conducting an experiment?
results of other experiments related to the subject.
