Volts and amperage together basically combined in a formula to determine the number of watts, but they are not specifically related to each other. As per Ohm's law V=IR where V is voltage, I is current and R is resistance. since Voltages is equal to current times resistance than makes them directly proportional to each other and therefor related.
Cervical Position. During menstrual bleeding, the cervix is normally low and hard and slightly open to allow the blood to flow out. It feels like the tip of your nose. After your period stops, the cervix remains low and hard and the opening to the uterus (uterine os) remains closed.
When there is no egg ripening in the ovary, the doorway to the womb (cervical os) is pinched shut to keep sperm out. In addition, the passage through the cervix (cervical canal) is blocked by a white sticky mucus, produced from glands inside the cervix.
