The modern 24-hour day cycle has its roots in ancient civilizations, but it was the Egyptians around 1500 BC who first divided the day into 24 parts, using sundials for daytime and water clocks for nighttime. This system was later adopted by the Greeks and Romans. The 24-hour format became more standardized with the advent of mechanical clocks in the Middle Ages, solidifying its use in the Western world by the 14th century. Today, the 24-hour cycle is widely recognized and used globally.

How can you determine your ovulation cycle when you have been on the pill for so long and you have not had a period in two years?

Why full eave rectifier rectifies negative half cycle?
the rectifier is Mainly used to convert the Ac current into DC current .In rectifier there are two diodes or (4 Diode In full wave bridge rectifier )are use is to conduct the current one is connected in forward bias(i.eD1) and the other is connected in reveres bias(i.eD2). As we know that the diode is conduct the current throw it When it is connected in forward bias . now when the voltage is applied to the circuit the the AC Current is start to flow throw circuit and in Positive half cycle of Ac current the Diode is Allow the current Pass throw it and during the Negative half cycle the Diode D2 is allow the current pass throw it and in these way the rectifier rectifies positive As Well As the negative half cycle
