What is the difference between high efficiency and low efficiency?

Efficiency describes how well a device transfers one form of energy to another form of usefull energy. High efficiency transforms most of the energy with very little loss. Low efficiency only transforms a small amount into usefull energy and the rest is usually lost to heat energy from friction. For example, a car is a low efficiency device because only a small amount (I forget the actual number. Probably around 50%) of the chemical energy in gasoline actually gets converted to energy of moving the car. The rest is lost to air resistance, friction between all the moving parts & and unused heat out the exhaust pipe.

What is the difference between low percent error and high percent error?
The difference between low percent error and high percent error is one is low and the other is high
What is the difference between high and low carbohydrates?
high carbs are when carbs are high and low carbs are when carbs are low.
What is the difference between high and low contrast?
The difference is that high contrast has more black and low contrast has more white.
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).
What is the difference between high oblique and low oblique?
High oblique includes the horizon and low does not.
What is the difference between low grade and high grade metamorphism?
One is high and one is low.
What is the difference between high quality and low quality energy?
The main difference between high quality and low quality energy is in the perception. This will facilitate the proper grading of tasks with the high tasks using high energy and low tasks low energy.
What is the rate of heat output of a Carnot engine?
Power Output / [(1/Thermal Efficiency) - 1], where Thermal Efficiency = 1 - Tc/Th
What is the difference between high relief and low relief?
The difference between high relief and low relief is that high relief has more depth and low relief is more casual and not as 3D. In high relief, it's much closer to 3D.
Describe why a high-efficiency machine is more desirable thana 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).
What is the difference between high and low humidity?
Low is at high temperature High is at low temperature It kind of has to do with the way the shower is at the humidity rate
What is the difference between the levels at high and low tide?
the diffrencce between high tide and low is a high tide is by the gravitaion pull of the moon and/or the sun and a low tide is in the middle between the moon an sun
