4. One technique for removing warts is to run an electrical current through them. The patient sits on a large, metal plate (called a “butt plate") and a metal needle connected to a power supply is touched to the wart. A current runs through the wart, heating it until it is removed. a. A large amount of energy needs to be delivered quickly. The resistance of human tissue is also large but the current is usually kept small. Given these facts, what can you predict about the voltage that is used? Why? b. Why does the patient need to sit on the butt plate (rather than on the plastic examining table)? c. Why (electrically) does the butt plate need to be large? d. How, if at all, will you need to change the voltage if you are removing a wart from someone's foot compared to removing one from the side of their hip? Why do you think so? You need to keep the amount of energy the same. e. Suppose you are removing a wart from a patient's lower leg. This patient has a metal rod running the length of…
