Why efficiency of generator is greater than motor?
i think both will be same..
Does an ideal machine would have an efficiency greater than one?
No, an efficiency greater than one would not be possible, since that would violate a very fundamental law of physics: conservation of energy. The efficiency of an "ideal machine" would be one, in many cases; the efficiency of an ideal Carnot engine would be less than one.
Why efficiency is greater then 1 in case of compound lever?
why efficency is greater than 1 in case of compound lever
Why can't the efficiency of a device or a process be greater than 100?
Efficiency cannot be greater than 100% because efficiency measures energy, and since energy is not made, only transfered (conservation of energy) then we cannot gain energy. Hence the energy out must be at most the energy in. Thus efficiency can be at most 100%
Can a machines efficiency can be greater than 100 percent?
nope, efficiency o fa machine cannot be greater than 100%...theoretically it shows sometime that efficiency of a machine can be 100%, but practically it cannot be possible as there is some loss of energy is always involved in different ways.
Why can't a pulley have a mechanical advantage greater than 1?
The mechanical advantage of a pulley can be greater than 1.The efficiency cannot but that is a different matter.
What is the efficiency of a heat engine is given by?
Efficiency is defined as output power divided by input power.The efficiency of a heat engine - for specific temperatures - cannot be greater than the efficiency of the theoretical Carnot engine.
Why do levers have a greater mechanical efficiency than simple machines?
The transmission lever is very simple and there is no friction.
Why do lever have a greater efficiency than other simple machines?
The transmission lever is very simple and there is no friction.
Are -14 and -23 negative integers prove your answer?
9
How do you prove that ten is a composite number?
All even numbers greater than 2 are composite.
Why do levers have a greater mechanical efficiency than other simple machines?
The transmission lever is very simple and there is no friction.
