Setting Up a Shock-Proof House Two years back when on one fine morning‚ I was taking my daughter to school in our car‚ we discovered that once a beautiful large house was now burnt black due to electrocution. Out of utmost dismay and wonder‚ my daughter asked me – “Papa‚ what has happened?”‚ and I provided her few explanations to what could have happened and how it could have happened. But her inquisitiveness was not resolved‚ and every other day in the morning‚ when we passed by that house

transistor is a semiconductor device that amplifies and switches electrical currents. They are the core component of any modern electronic devices‚ such as computer‚ telephones and other electronics. Nowadays most transistors are use to produce integrated circuits. There were a numerous inventions‚ or problems with the inventions that lead to the birth of the transistor. Radio signals‚ could be sent carrying information over a long distance away; the only problem was there was no device to receive the signal

applications. During this time the first electronic digital computers were developed. Originally they were the size of a large room‚ consuming as much power as several hundred modern personal computers (PCs).[1] Modern computers based on integrated circuits are millions to billions of times more capable than the early machines‚ and occupy a fraction of the space.[2] Simple computers are small enough to fit into mobile devices‚ and mobile computers can be powered by small batteries. Personal computers
Premium Computer Microprocessor Integrated circuit
the Q of a resonant circuit causes its bandwidth to increase. 3. Good selectivity usually means narrow bandwidth. 4. True. A tuned circuit can provide voltage gain. 5. Cascading tuned circuits cause the selectivity to increase. 6. If the selectivity of a tuned circuit is too sharp‚ the sidebands of the received signal may be attenuated. 7. A tuned circuit has a Q of 100 at its resonant frequency of 500 kHz. Its bandwidth is 5 kHz. 8. A parallel LC tuned circuit has a coil of 3µHz

at least three terminals for connection to an external circuit. A voltage or current applied to one pair of the transistor’s terminals changes the current flowing through another pair of terminals. Because the controlled (output) power can be much more than the controlling (input) power‚ the transistor provides amplification of a signal. Today‚ some transistors are packaged individually‚ but many more are found embedded in integrated circuits. The transistor is the fundamental building block of modern
