Porosity is the measure of empty spaces in a material, often used in geology and engineering.

• Porosity is the ratio of void spaces to total volume in a material.

• It is expressed as a percentage.

• Porosity is important in fields like geology for assessing rock formations and in engineering for determining the strength of materials.

• Examples of porous materials include sponges, pumice stones, and aerogels.

Permeability is the property of a material that allows fluids or gases to pass through it.

• Permeability is a measure of how easily a substance can pass through a material.

• It is often used in geology to describe how easily fluids can flow through rocks or soil.

• Permeability can be affected by factors such as pore size, connectivity, and fluid viscosity.

• Materials like sandstone have high permeability, while materials like

Oil shale is a rock containing kerogen that can be converted into shale oil through a process called retorting.

• Oil shale is a sedimentary rock containing kerogen, a precursor to oil.

• Shale oil is the liquid hydrocarbons extracted from oil shale through a process called retorting.

• Oil shale deposits are found in various countries like the United States, Estonia, and China.

A transformer is a device that transfers electrical energy between two or more circuits through electromagnetic induction.

• Transformers are used to increase or decrease voltage levels in electrical circuits.

• They consist of primary and secondary coils wound around a core made of ferromagnetic material.

• Step-up transformers increase voltage for long-distance power transmission, while step-down transformers decrease voltage...read more

The unit of resistance is ohm (Ω), named after German physicist Georg Simon Ohm.

• The unit symbol for resistance is Ω

• Resistance is measured using an ohmmeter

• 1 ohm is equal to 1 volt per ampere (V/A)

The unit of current is Ampere (A)

• The unit of current is named after the French physicist Andre-Marie Ampere

• 1 Ampere is defined as the flow of 1 Coulomb of charge per second

• Commonly used prefixes for current include milliampere (mA) and microampere (μA)
