The critical value is not the height of the dam itself but the height, or "head" of water inlet above the turbine.
The higher the head the greater the pressure available, so provided it's also matched by sufficient flow the greater the power output.
To illustrate the first point, a 30m high dam will produce the same power output from a given generating set level with its base, as a 5m high dam whose turbo-alternator is 25m lower in altitude down-valley - neglecting flow losses by fristion in the longer pipe-line. It's still 30m head even though the dam wall is far lower.

What is the amount of energy generateydropower source is depend on?
The amount of energy generated by a hydropower source depends on the flow rate of water and the height from which it falls, known as the head. The higher the flow rate and head, the more energy can be generated by the hydropower source.
Does a height of a dam make a difference on the amount of energy the dam produce?
Yes, the height of a dam, known as its head height, directly impacts the potential energy available to generate electricity. A taller dam with a greater head height will have more gravitational potential energy to convert into electricity through turbines, resulting in higher energy production.
What is the wave energy formula used to calculate the amount of energy generated by ocean waves?
The wave energy formula used to calculate the amount of energy generated by ocean waves is: E 0.5 A H2 T where: E wave energy (in joules) water density (in kg/m3) A wave amplitude (in meters) H wave height (in meters) T wave period (in seconds)
Will different heights affect the bounce of the ball?
The height you drop the ball from will affect the bounce height this is because as the drop height increases so does the bounce height it is all to do with energy transfers. Also the waste energy is the sound and heat energy hope this helps.
What two factors affect potiental energy?
The two factors that affect potential energy are the mass of the object and its height above the ground. As an object's mass or height increases, its potential energy also increases.

What factors affect the amount of gravitational potential energy?
Mass, gravity, height.
What will affect the amount of gravitational potential energy?
The mass, height and the force of gravity at the location.

Why does the height affect the loop on a marble rollercoaster?
I would have gravitational potential energy, which is energy due to height.

The two factors that affect potential energy are the mass of the object and its height above the ground. As an object's mass or height increases, its potential energy also increases.
What variables affect the amount of GPE something has?
The amount of gravitational potential energy (GPE) an object has is influenced by its mass, height above a reference point, and the acceleration due to gravity. GPE is calculated as mass multiplied by height multiplied by the acceleration due to gravity.
How does height affect acceleration?
Height does not directly affect acceleration. Acceleration is determined by the force applied to an object, its mass, and any friction or air resistance. However, height can influence potential energy, which can be converted into kinetic energy and affect the speed of an object as it moves downhill.
When does a coaster have a large amount of Kinetic Energy and when does it have a large amount of Potential Energy?
The coaster have a large amount of potential energy when it gain height, kinetic energy when it gain speed instead.
How does changing the height of the ramp affect the kinetic energy?
Changing the height of the ramp will affect the potential energy of the object on the ramp. As the height increases, potential energy also increases. When the object moves down the ramp, potential energy is converted to kinetic energy. Therefore, a higher ramp will result in higher kinetic energy at the bottom of the ramp.
