Electric current originates from which part of an atom? *

Engineering
1 answer:
yanalaym [24]3 years ago
3 0

Answer: Electric current originates from positively charged protons negatively charged electrons of an atom.

Explanation:

The movement of ions (positive or negative) from one point to another is called electric current.

An atom has three sub-atomic particles. These are protons, neutrons and electrons.

Protons are positively charged, neutrons have no charge and electrons are negatively charged. Protons and neutrons reside inside the nucleus of an atom whereas electrons revolve around the nucleus.

So, protons and electrons are responsible for originating electric current form an atom as these are the charged particles.

Thus, we can conclude that electric current originates from positively charged protons negatively charged electrons of an atom.

Which of these is not applicable to tuning for some Overshoot on Start-up? Select one: 1)-No overshoot during normal modulating
alekssr [168]

Answer: 5) KC-0.78 KU

Explanation:

 KC-0.78 KU is not defined for tuning of overshoot on the Start-up as, this method is only applicable for there is some turning constants and also there is no overshoot during the normally modulating control. But some overshoot at start up are applicable. For the continuous cycling method, some overshoot is same as for closed loop tuning.

A generator that produces 40 kilowatts uses twice as much fuel in an hour as a generator that produces 20 kilowatts. Explain why
mars1129 [50]

Answer:

In terms of energy conversion/transformation the generator that produces 40 kilowatts of power will consume twice as much fuel than a generator that produces 20 watts because the more electrical power produced by an electrical generator, the more fuel is consumed. The amount of electrical energy produced is directly proportional to the fuel consumed.  

Explanation:

Energy transformation is the conversion of energy from one form to another. Their are various forms of energy namely kinetic energy, electric energy, mechanical energy , chemical energy , solar energy, heat energy , nuclear energy. These energy can be transformed from one form to another . Example our body convert chemical energy through food we eat to mechanical energy.  

The generator transforms  mechanical energy into electrical energy . The kilowatts tells you the amount of power the generator produces .The energy is measured in kilowatts per hour which is the power used over a period of time.

In terms of energy conversion/transformation the generator that produces 40 kilowatts of power will consume twice as much fuel than a generator that produces 20 watts because the more electrical power produced by an electrical generator, the more fuel is consumed. The amount of electrical energy produced is directly proportional to the fuel consumed.   So far the generator conversion efficiency are equal  for both generators the generator with the higher power generation will consume more fuel per hour.

2. the length of the bridge.

3. The dynamic and static load to which the bridge will be subjected.

4. How corrosive is the environment where it will be built.

5.wind forces

6. The force due to possible earthquakes.

7. If it is going to be built in an environment where snow falls.

8. The bridge is unique,so   the shape has a geometry that resists loads?.
