Answer / rameez rehman

It is difficult to transform direct current from one voltage
to another; hence, initially DC had to be transmitted at the
low voltage at which it was generated and used. This fact
limited its applicability: if transmission of large amounts
of electricity or transmission over long distances was
required, the cost of the conductor (copper wire) was
prohibitive. Alternating current may be generated at a low
voltage, boosted to a higher voltage by a transformer,
transmitted and converted back to a lower voltage before use.

vry much losses accour due to transsmission of dc.

why does the current through inductor is constant, why current through inductor & voltage across capacitor is constant? can u explin clearly?

interface an 8-pin switch with 8085 microprocessor located at 0AAH and LEDs at port 55H, draw the circuit diagram. Write down a program to read the switches and do the following: > if the parity of the switch is odd, start counting upward until it reaches 0FFH. > if the parity of the switch is even, start counting downwards until it reaches 00H.
