Electical Definition and 19 Threads

An officer-elect refers to a person who has been elected to a position but has not yet been installed. For example, a president who has been elected but not yet installed would be referred to as a president-elect (e.g. President-elect of the United States).
Analogously, the term -designate (e.g. prime minister-designate) is used for the same purpose.

    What causes voltage between AC Mains phase and me?

    So my question is that if i put other lead of multimeter to my hand and other lead to socket 230 phase wire why it shows 150 volts when i stand at floor and 80 volts when i stand at carpet? what causes those voltages? And yes i know doing that could be dangerous. It also shows weird voltage if i...

    Object detector using ultrasonic sensor with 555 timer

    See the attached figure. I used 220uF with buzzer and also tried 10uF capacitor but buzzer isn't loud enough. I don't have any 3.3pf capacitor. I used 1.1 pF instead. I also tried changing the resistance of potentiometer but still buzzer isn't sound loud enough.

    Salt bridge and electical field

    Is it correct that a salt bridge in a Galvanic cell makes that there is no electrical field between the solutions of the two hallf cells? Does that mean that the electrical potential (I do not write electrochemical potential) between both solutions is zero in an ideal world? Is it also possible...

    Nodal Analysis Problem help (Double Supermesh)

    That is, for Supernode -1,3 (12V branch) , we do Nodal Analysis and we have (V2-V3)/2 , over the 2 ohm branch. But this current is not included in the Equation 1 in the solution I have attached(Which is my only source to cross check answers/solution right now.) Is the solution wrong? Thanks...

    Using a generator to charge 2 batteries

    My project is to create a circuit for a stroller that can store the mechanical work into electrical while moving around and with the push of a switch, use the electrically stored energy to assist the movement of the stroller. I’ve tried capacitors but it ended up not being enough voltage and I...

    Programs Double Degree in Physics and Electical Engineering?

    Hi! I'm about to take my senior year in high school, and I was originally planning on taking electrical engineering plus some extra classes in physics. I like to work with my hands and to create things, so engineering is sort of a no-brainer for me, but it's also very important for me to...

    What is the Significance of the Electric field in a closed circuit

    Hi, I am confused about the electric field lines which are depicted mostly on the Internet as per conventional way. What I understand that the conventional current was due to positive charges which was wrong. Actual flow of the current was due to the negative charges or electrons. When the...

    Troubleshooting Car Electrical Issues: Understanding Grounding and Wattage

    1. I have a car that has some electrical/electronic weirdness; the basic issue is apparently parasitic draw of about 2.5amps @ 12v. When I connect the (problematic) component the chassis ground (connected to battery ground) what I observe is that the battery chassis jumps from 0v to something...

    Electical shock, electrocution questions

    HI, I couldn't decide which forum was the best to post these in. I have two questions regarding electricity and getting shocked, or electrocuted. 1. Being shocked from the spark plug leads on either small engines (lawnmowers) or cars. Classically, on either of these, you have a coil which...
