The first law of thermodynamics states that energy cannot be created or destroyed, only transformed. In the case of a light bulb, electrical energy is converted into light and heat energy. The second law of thermodynamics states that some energy is always lost as heat in any energy conversion process, thus not all the energy from the light bulb is converted into light.

What law of thermodynamics is unavailable for doing work?
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
Whose work on heat engines lead to the formulation of the second law of thermodynamics?
The work of Sadi Carnot, a French engineer, on the efficiency of heat engines in the early 19th century led to the formulation of the second law of thermodynamics. Carnot's insights on the limitations of heat engine efficiency laid the foundation for the development of the second law, which eventually became a fundamental principle in thermodynamics.
What law of thermodynamics accounts for the other 75 units of energy?
The way that the question is worded it is impossible to be sure exactly what you are looking for, but as a reasonable guess, you are looking for what happens to energy that is not producing useful work. The second law of thermodynamics generally tells us that we can never get 100% efficiency, i.e. we can never convert all the energy we are using into useful work. Some of the energy will just go into increasing the entropy of the universe.

Second Law of Thermodynamics
Is an electric current that flows through a tungsten wire in a light bulb creating a glow an example of the 1st or 2nd law of thermodynamics?
It really shows both but the relationship to the 1st law is a lot more obvious.The light coming from the glowing wire is an example of energy. By the first law, that energy must have come from somewhere - in this case the electricity passing through the wire with some of that energy being converted to light. As soon as you quit supplying power to it, the wire will cool down and quit glowing - no energy input in the form of electricity means no output of energy in the form of light (and heat).The wire glows because it is getting hot. The second law dictates that as the energy moves through the wire, some of it will be dissipated in the form of heat. This relates to the 2nd law. The reasons why it has to dissipate as heat go into electron orbitals, inter-molecular forces and a bit of quantum physics which are outside the scope of this answer.
What law of thermodynamics is unavailable for doing work?
"Unavailable for doing work" is related to the Second Law of Thermodynamics.
How do you work out the current of a light bulb?
You can use Ohm's Law to calculate the current of a light bulb by dividing the voltage across the light bulb by its resistance, which is typically provided on the bulb itself or its packaging. The formula is: Current (I) = Voltage (V) / Resistance (R).
What conversion does the second law of thermodynamics not allow?
The second law does not allow complete conversion of heat into work.
How does entropy work in the context of thermodynamics and the second law of thermodynamics?
Entropy is a measure of disorder or randomness in a system. In the context of thermodynamics and the second law of thermodynamics, entropy tends to increase over time in isolated systems. This means that energy tends to disperse and become less organized, leading to a decrease in the system's ability to do work. The second law of thermodynamics states that the total entropy of a closed system will always increase or remain constant, but never decrease.
Which law of thermodynamics states that the heat engine cannot be completely efficient?
True
When the law of conversation of energy is applied to heat it is known as the law of thermodynamics?
Not exactly. The first law of thermodynamics, i.e. the law of conservation of energy, also accounts for heat as one of the many forms that energy can take. There is no one law called "the law of thermodynamics", but there are several "Laws of Thermodynamics" (note the plural form "LAWS").
On which thermodynamic law a thermodynamics cycle based?
Thermodynamic cycle is based on 2nd law of thermodynamics.
Why bulb related to physics?
When electricity passes through the filament of a standard light bulb, the electrons collide with the metal atoms present there, producing heat. When an object gets hotter, it causes light to be emmited by electrons transitioning in their atomic orbitals. Heat, light, electricity, all of these are governed by physics.
How is the thermodynamics process related to the 1st law of thermodynamics?
Magic
Of thermodynamics is a restatement of the law of conservation?
The 1st Law of thermodynamics is a restatement of the law of conservation of energy.

What is another name for the first law of Thermodynamics?
The first law of thermodynamics is also known as the Law of Energy Conservation.
