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.
The term erosion means that the tender cells lining the neck of the womb have formed a rather delicate and fragile rim around its opening and, though most women with cervical erosion have few symptoms, it may bleed when touched. So Angela wasn't perturbed when she was told she was suffering from cervical erosion.
