stick to DC and AC where the voltage exceeds a specific limit and if current flow path is there .
AC or alternating current has the tendency to flow on the outer skin of a person also at some time the potential will be zero. On DC current flow trough a person body basically cooking organs and causing damage

DC, or Direct Current, was not invented in the traditional sense as it is a very simple and common way to transfer power through a conductor. Far too common to pinpoint the first person who discovered it. Thomas Edison developed direct current, but it was only with Nikola Tesla's help that Edison ever developed any useful generators for direct current. It's odd that we credit Edison with inventing the light bulb AND direct current when Nikola Tesla is to direct current what Edison is to the light bulb.
The person being interviewed is the interviewee. The person conducting the interview is the interviewer.
When conducting an experiment in a laboratory environment, the person conducting the experiment and the Instructor or Principle Investigator are responsible for ensuring that appropriate safety procedures are followed.
A primary source is an original material or firsthand information that provides direct evidence of an event, object, person, or work. Examples include documents, photographs, artifacts, interviews, and original research studies. These sources offer firsthand accounts or direct evidence of an event or topic of study.
Batteries range in output voltage from 1.2 volts for an AA rechargeable, to 12 volts for a car battery. There may be other voltages, for special purpose applications. Batteries supply DC (direct current), meaning that the current will only flow in one direction.What is considered "mains" electricity (from a plug or receptacle in the wall) is alternating current (the current is oscillating between flowing one direction, then the opposite direction then back and repeats). It oscillates at 50 or 60 times per second, depending on what country you live in. Also the voltage is between 100 volts and 250 volts, depending on the country, as well. These features enable the voltage to be changed up or down rather easily with transformer, and allow the electricity to be transmitted over long distances.But the alternating current and higher voltages also make your mains electricity much more dangerous to touch than a battery. A person's skin has pretty good resistance to electric flow, especially direct current. But with alternating current, if you touch a wire, charges can actually form under the skin and start flowing through your body, because your skin acts as a capacitor. Then, the oscillating current back and forth through your organs is much more damaging, possibly causing your heart to stop pumping.
The direct descendents of a person are that person's children, grandchildren, great-grandchildren, etc. The direct descendents can trace their ancestry directly back to the person. For example, you are your great-great-grandmother's direct descendent, but you are not the direct descendent of your great-great-grandmother's sister.

A direct address refers to someone speaking to or about another specific person. When you are having a conversation with just one other person, this is direct address.
Your direct supervisor-person immediately above you.
An apparatus for reducing or increasing the voltage of an alternating current.A person or thing that transforms something.
