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.
During the two-four days prior to ovulation the cervical mucus changes from being cloudy and either dry, runny or yoghurty and therefore pre-ovulatory, to the classical clear, stretchy egg-white discharge which we all recognise. At the same time the cervix changes postion, and the os, the entrance to the cervix, opens wider.
