Ohm's law states that the current through a conductor between two points is directly proportional to the potential difference across the two points. Introducing the constant of proportionality, the resistance, one arrives at the usual mathematical equation that describes this relationship:
Total hysterectomyâThe entire uterus, including the cervix, is removed. Supracervical (also called subtotal or partial) hysterectomyâThe upper part of the uterus is removed, but the cervix is left in place. This type of hysterectomy can only be performed laparoscopically or abdominally.
1 A total hysterectomy is the removal of the uterus and cervix.  A total hysterectomy with bilateral salpingo-oophorectomy is the removal of the uterus, cervix, fallopian tubes, and ovaries. This is the most common surgery done for endometrial cancer.
