Electrical Vs Electronics

Electrical definition- Objects which takes electricity and turns it into some other form of energy like light, motion, heat, anti heat, etc.

Electronic definition- Objects which for the most part has some type of computer controlling these objects, and or objects like transistors, diodes, and integrated circuits.

Electronic circuits have the ability of precessing things whilst electronics do not have this ability.

List of disadvantages NYC faced in switching to electronic traffic lights

  • The traffic lights throughout the city can be hacked through a computer and that can cause major disasters.
  • People would have to be retrained to learn how electronic lights work from once knowing how they work through an electric point of view.
  • This costed a lot of time and money to install these new electronic lights.

 

List of advantages NYC faced in switching to electronic traffic lights

  • No one well need to go to each individual traffic light pole and fix the wiring to fix the light.
  • Traffic will flow smoothly with an automated timed, computerized light controlled system.
  • It will improve the safety of people if the lights work properly 95% percent of the time.
  • Traffic lights can be fixed quicker if someone is always monitoring the NYC traffic lights in a certain area.

 

I think NYC did the right thing in changing a lot of NYC traffic lights to be electronically instead of electrical because, driving becomes smoother meaning less accidents and more safety, hence less traffic; which is always a good thing! If a problem come ups with a light, the fixing of the light would come quicker because it is electronically controlled instead of electrically controlled.

Positive energy flows from the positive lead of the battery and then goes through the switch if the switch allows it to, and then the flow energy continues until it hits a resistor in which the resistor limits the amount of energy going into whatever it is powering. The thing gets powered and in this case it is a red led and then negative energy goes back into the battery.

Electrical Safety

1st. Metal is a great conductor of electricity

  • Don’t wear metal jewelry or watchbands when working on electrical circuits.
  • Use tools with non-conducting handles.
  • When possible, work on electrical circuits with 1 hand, keeping the other away from conductive materials.

2nd. Another decent conductor of electricity is water

  • Never work with electrical circuits with wet hands or on a wet floor.
  • If there is a spill, shut off the main power before doing anything else.

3rd. A so-so conductor of electricity are humans

  • Don’t touch electrical circuits with your fingers.
  • Treat all electrical devices as if they are energized.
  • Disconnect the power source before working on electrical circuits and devices.
  • When possible, work on electrical circuits with 1 hand, keeping the other away from conductive materials.
  • Should someone come into contact with electricity, don’t touch them; shut down the main power.
  • Never touch anyone’s electrical circuits unless invited to do so.
  • Enclose all electrical contacts and conductors.
  • Always de-energize electrical circuits when done working with them.
  • Do not wear loose or hanging clothing near electrical equipment.
  • Always drain capacitors before working near them.
