Q. Explain Read-only memory?
ROM is nonvolatile (because it maintains its contents even when its power is shut off) and is used to store data and programs that do not change during the operation of the system. The mask-programmed ROMs are read-only devices that are programmed for data storage during the manufacturing of the chip itself. These are generally less expensive devices for mass production. Character-font memory for laser printers is a good example. Programmable read-only memory (PROM) is a field-programmable memory that is fabricated by the manufacturer containing all 0s and is programmed irreversibly by the user by electrically changing appropriate 0s to 1s. PROMs are quite economical in small quantities. Erasable programmable read-only memory (EPROM) is nonvolatile and widely used in microprocessor systems for program storage. It can be erased by shining an ultraviolet light and reprogrammed if necessary. These are produced in lowtomoderate volumes.

Q. The energy stored in a 2-µH inductor is given by w L (t) = 9e -2t µJ for t ≥ 0. Find the inductor current and voltage at t = 1 s.
Q. Describe about Boltzmann constant? The constant η in Figure (b) stands for the noise power spectral density, expressed in terms of power per unit frequency (W/Hz). Statistic
Consider an electromagnet, as shown in Figure, which is used to support a solid piece of steel and is excited by a coil of N = 1000 turns carrying a current i = 1.5 A. The cross-se
Explain protected mode interrupt. In this mode, interrupts have exactly similar assignments as in real mode, but the interrupt vector table is not same. In place of interrupt

i want circuit theory relavant assingment sir please immediately
I have a closed loop or feedback system and i want to convert it into electrical circuit. please give me example about this
1) only one pair of slip rings are required (to energise the rotating field coil) regardless of the number of phases produced by the alternator (three phases is common because of t
