Intro To Capacitors
A capacitor stores electric charge by having two conductors separated by an insulator. The amount of charge stored is proportional to the potential difference between the conductors. Capacitance is a measure of how much charge can be stored at a given potential difference. Parallel plate capacitors have capacitance that depends on the area of the plates and their separation distance. Dielectrics between the plates increase capacitance.

An atom is the basic building block of chemistry. It is the smallest unit into which matter can be divided without the release of electrically charged particles. It also is the smallest unit of matter that has the characteristic properties of a chemical element
5.3 electric cells
1. Batteries work by using a chemical reaction to create a difference in electrolytic potential between two terminals placed in an electrolyte. This potential difference causes ions to flow from one terminal to the other.
2. Primary cells cannot be recharged, while secondary cells can be recharged by applying an external voltage to reverse the chemical reaction.
3. The electromotive force (EMF) of a source is the electrical potential energy, measured in volts, that is transferred to each coulomb of charge passing through the source. Common examples of sources that provide EMF include dry cells, dynamos, and solar cells.

This experiment will correct the five false premises made by early scientists
who evaluated Faraday's Electric Magnetic Rotation Apparatus (motor)
False premises made by early scientists who evaluated Faraday's Electric Magnetic Rotation Apparatus (motor) โ which still exist today 197 years later.
False premise # 1) Electrical energy can be transformed into mechanical energy.
True statement: Electrical energy can not be transformed into mechanical energy in electric motors, it can only be converted to heat energy and dissipated as heat energy due to the resistance of the wire used. Electric motors do not rotate due to heat dissipation.
False premise # 2) Electrical energy is required to create the magnetic field around a current bearing wire.
True statement: Electrical energy is not required to create the magnetic field around a current bearing wire.
The magnitude of current flow in a current bearing wire is dictated by the Electromotive Force (voltage) applied across the wire and the DC resistance of the circuit according to the equation I = E/R.
Some electrical energy is converted to heat (loss) due to the current bearing wire's DC resistance but there is no energy consumption related to the production of the magnetic field which is created for free.
False premise # 3) Electric motors convert electrical energy to heat energy and mechanical energy.
True statement: Electric motors do convert electrical energy to heat energy but they do not convert electrical energy to mechanical energy.
The equation, P = I^R dictates mathematically how much electrical energy is converted to heat energy in the motor's current bearing wire.
100% of the energy consumed in the motor is due to heat conversion.
0% remains mathematically to produce any mechanical conversion.
False premise # 4) Electric motors operate at less than 100% efficiency in their conversion of electrical energy to mechanical energy.
True statement: Electric motors operate at 100% efficiency in their conversion of electrical energy to heat energy.
The mechanical energy which is produced by an electric motor is provided by the magnetic field energy which is created around the current bearing wire with zero energy cost consumption and at infinite efficiency.
All electric motors operate at infinite efficiency in their production of mechanical energy / magnetic rotation and 100% efficiency in their conversion of electrical energy to heat energy.
False premise # 5) Energy cannot be created but can only be converted from one form to another.
True statement: The magnetic fields that are created around a current bearing wire are a form of energy โ which is created because they perform work and change the kinetic energy of the current bearing wire according to the Work Energy Principle.
Energy (magnetic field energy) can and is being created around every current bearing wire.
Energy can be created.

chemical Reactions in Battieries
- Benjamin Franklin first coined the term "battery" in 1749 to describe linked capacitors, though batteries existed prior, like the Baghdad Batteries from 2000 years ago.
- Luigi Galvani first described "animal electricity" in 1780 by creating a current through a frog, unknowingly demonstrating a type of battery. Volta built the first real battery, the voltaic pile, in 1800.
- Major battery developments followed, including the first rechargeable lead-acid battery in 1859 and the first dry cell battery in 1887. The common alkaline battery was introduced in 1955 and lithium-ion batteries became widely used in the 1990s.
5.3 electric cells
1) Batteries work by using a chemical reaction to create a difference in electrolytic potential between two terminals placed in an electrolyte. Ions are attracted to the opposite terminal, creating a flow of electricity.
2) Primary cells cannot be recharged, while secondary cells can be recharged by applying an external voltage to reverse the chemical reaction.
3) There is a potential difference (p.d.) or voltage across any component that converts electrical energy to other forms like heat or light. P.D. is measured in volts and represents the electrical potential energy lost per coulomb passing between two points.

3 CORRECTIONS to Michael Faraday's Electric Magnetic Rotation Apparatus (Moto...Thane Heins Regenerative Acceleration Generator Technology
Michael Faraday's 1822 experiment with an electric motor is recreated to correct misunderstandings from early scientists. The experiment uses a mercury bath, wire, magnet, and battery. It is found that the power dissipated as heat in the circuit is the same both with and without rotation of the wire. This shows that electrical energy is only converted to heat in the wire due to resistance, and not to mechanical energy. The rotation is caused by magnetic field energy created around the wire without energy cost. Faraday thus proved that magnetic fields can perform work without cost, and motors operate at infinite efficiency through magnetic fields rather than transforming electrical energy.ย

How to Manage Reception Report in Odoo 17
A business may deal with both sales and purchases occasionally. They buy things from vendors and then sell them to their customers. Such dealings can be confusing at times. Because multiple clients may inquire about the same product at the same time, after purchasing those products, customers must be assigned to them. Odoo has a tool called Reception Report that can be used to complete this assignment. By enabling this, a reception report comes automatically after confirming a receipt, from which we can assign products to orders.
How to Setup Default Value for a Field in Odoo 17
In Odoo, we can set a default value for a field during the creation of a record for a model. We have many methods in odoo for setting a default value to the field.
