Depends on the power station. For fossil fuel/thermal : chemical to kinetic to hear to kinetic in turning turbines and finally into electrical
And there was an mcq on this from some year i cant ... remember...
Thnx for dat
also i wanted to know that which energy is greatest at the mid-point of pendulum n at its highest point?
Thnx for dat
Bistable and stable? What are those? The logic gates :/.. emm can someone explain why electromagnetic waves are easily absorbed when their wavelengths are short and they are at high frequencies.....like Gamma rays ... they are dangerous while radio waves can easily pass through atmosphere without much absorb....
And have you done Transistors, Bistable and Astable circuits... the optional part of syllabus...
Metal casing would become live because the earth and the live wire are connected at exactly the same point
Casing becomes live as the earth wire (green n yellow) is connected wrong. It shud b connected in the middle of the plug
For that u have to learn the whole order of spectrum. Waves upwards have low frequencies n larger wavelengths. These r usually harmless as infrared r used in remote controls as well. Waves down have high frequency n short wavelength, which makes them dangerous. These include the gamma rays and ultrasonic waves. I have studied transistors, but bistable n astable :/ never heard of it.. emm can someone explain why electromagnetic waves are easily absorbed when their wavelengths are short and they are at high frequencies.....like Gamma rays ... they are dangerous while radio waves can easily pass through atmosphere without much absorb....

Logic gates r the "ratta wali thing"
They r the different arrangements of inputs n outputs in a circuit. Three Basic gates r AND, OR, NOT. Other 2 gates r combinations of basic gates. They r NAND n NOR. For more help, try these notes.
Relay circuit is one in which a small change in current or voltage controls the switching on n off of the circuit or other devices. Circuit breaker is an example of a relay circuit. When current becomes high inside, soft iron bar is magnetised and it attracts the iron armature in the circuit, closing the circuit. A magnetic relay switch is a device used to control a large current output circuit with the help of small current input crcuit. In this also, an electromagnet is used.

thankuuuuu so muchhhLogic gates r the "ratta wali thing"
!!
No prob at allt
thankuuuuu so muchhh
its B
For almost 10 years, the site XtremePapers has been trying very hard to serve its users.
However, we are now struggling to cover its operational costs due to unforeseen circumstances. If we helped you in any way, kindly contribute and be the part of this effort. No act of kindness, no matter how small, is ever wasted.
