What is the condition for maximum efficiency of a DC machine?

The condition for maximum efficiency of a d.c. machine is that VARIABLE LOSSES must be equal to CONSTANT LOSSES i.e., variable losses = constant losses..


How do you determine machine efficiency?

Machine efficiency is typically determined by calculating the ratio of useful output to input. This can be done by comparing the actual output of the machine to its theoretical maximum output under ideal conditions. Factors such as energy losses, downtime, and maintenance can also affect machine efficiency.


What is the maximum efficiency of a machine?

The maximum efficiency of a machine is 100%, which means that all input energy is converted into useful output energy without any losses. However, achieving 100% efficiency is practically impossible due to factors such as friction, heat loss, and other inefficiencies in real-world systems.


Why is the efficiency of 1.0 is not achievable?

In any machine, some energy will usually be wasted. This will reduce the efficiency below the theoretical maximum of 1.0. However, please note that, if the efficiency is above 95% (or 0.95), when rounded to the nearest tenth you will get 1.0.In any machine, some energy will usually be wasted.

Why would a machine with 100 percent efficiency be considered an ideal machine?

No heat loss = maximum output. There would be no loss of energy, which is an ideal condition.


How do you use the word orchestrated in a sentence?

The plan was carefully orchestrated to insure success. He orchestrated every movement to get the maximum efficiency from the machine.


What is the maximum efficiency any machine can have?

Mathematically, efficiency = (energy output) divided by (energy input) as a percentage. As if we couldn't figure this out for ourselves, one of the laws of Thermodynamics formally tells us "You can't get more energy out than what you put in." Applying this law to the formula for efficiency, it says that the maximum possible efficiency is 100%. However, the next law of Thermodynamics says "You can't even get that much out."


Why is a high efficiency machine is more desirable than a low efficiency machine?

A high efficiency machine will produce more of what is it that you want with the same power as the low efficiency one. In other words, for a low efficiency machine do as much as a high efficiency one, you have to give it more power (energy).


When is the efficiency maximum in a transformer?

the efficiency is maximum in a transformer when no load loss is equal to load loss.


The efficiency of a machine is usually expressed in?

The efficiency of a machine is usually expressed as a percentage. The ideal efficiency of a machine is 100-percent.Another AnswerThere are no units of measurement for efficiency, because you are comparing like with like: output power divided by input power.


Why are distribution transformers frequently designed to develop maximum efficiency at loads that are somewhat lower than rated value?

It is always desirable to run any equipment or device at maximum efficiency for that matter, not only the power transformer. Power transformer maximum efficiency occurs when copper loss is equal to iron loss. (or no load loss equals to load loss). This does not necessariliy mean that maximum efficiency occurs at maximum or full load. Generally the maximum efficiency occurs at relatively less than full load of the transformer.


What can be done to increase the efficiency of the machine?

Mechanical Efficiency is the ratio of Actual mechanical advantage to ideal mechanical advantage.Efficiency will be maximum when Actual mechanical advantage equals that of ideal.But practically not possible.Actual mechanical advantage will be less due to friction,heat,deflection etc.avoiding these loses will increase the machine efficiency.
