From an engineers point of view how do you explain three phase electrical systems to someone that has no idea how it works?
First visualize a sine wave. It undulates between positive and negative voltage in a form that looks like the wave that ripples out when you drop something onto still water. If you took a picture across a slice through multiple ripples you would see a positive hump and then its negative image. So the wave is gradually rising to a peak and then falling to a valley. If you superimposed two such waves upon each other and they matched perfectly where they crossed zero and where they peaked positively then the waveforms would have the same frequency and would be in phase.
If you took these in phase waveforms and then slid one over the other so that the positive and negative peaks occurred at the same time the waveforms would be 180 degrees out of phase. In a three phase system the peaks of three waveforms are each one third cycle from the other or 120 degrees out of phase with each other.
In a three phase system each waveform is on separate wires so that you can either run a device such as a motor that runs on 3-phase power or you can add different phases together to get different voltage outputs or use each voltage separately as single phase services.

What do car engineers do?
The car engineers develop parts of the car, like electrical and mechanical systems.
Are low-voltage systems totally safe Explain?
No, Their are no electrical systems that are totally safe. Elections harness electricity not control it.
What is electrical engineers demand?
The demand for electrical engineers remains strong due to the ongoing advancements in technology, renewable energy, and telecommunications. Industries such as electric power generation, electronics manufacturing, and automation are actively seeking skilled professionals to innovate and improve systems. Additionally, the push for sustainable energy solutions and smart grid technologies further fuels the need for electrical engineers. Overall, job prospects in this field are expected to grow, driven by technological progress and infrastructure development.
What is the difference between engineer and technician?
The difference between Engineers and Technicians is not that one is more hands-on or practical than the other. Rather, the fundamental difference between the two is that Engineers develop/design systems while Technicians support those systems. As such, Engineering and Technology are complementary fields. Engineers need to start from a theoretical framework in order to develop/design systems while technicians need to understand how those systems work in order to support them. That fundamental difference between Engineering and technology not only explains how or why engineers tend to rise to top management but also gives engineers a career advancement advantage because engineers by designed manage the development and implementation of their systems, which are to be supported by technicians.
