Electricity

• elektron - amber
• Electricity - one of the basic forms of energy
• Electricity - associated with charges
• Electricity - can be generated in many ways (used, showed, harvest, transfer, stored)
• Types of Electric Charge: Conductors and Insulators
• Conductors - materials that permit electrons that flow freely from particle to particle
• Insulators - materials that impede the free flow of electrons from atom to atom and molecule
• Static (Non moving charge) - charges in which they stay in one place
• Moving (Current charge) - flow of electric charge from one point to another
• Conduction - charging with contact, transfer of energy
• Induction - charging without contact
• (+)(-) charges = attraction
• (+)(+), (-)(-) charges = repulsion
• The flow of electricity is negative to positive
• The closer the charges are, the higher electric force
• Coulomb Law - the electrical force between two charged objects is directly proportional to the product of the quantity of charge on the objects and inversely proportional to the square of the separation distance between the two obejects.
• Micro coulomb - 1x10^6
• Nano coulomb - 1x10^9
• Electric Field - a field around a charge that exerts a force on other charges
• Electric Field - the influence of electric charges on other charges in the space around them
• Electric Field - the force experienced by a positive test charge placed at that point
• Positively charged - flow of electric field is outwards
• Negatively charged - flow of electric field is inwards
• Electric field strength is a vector
• Electrical Potential Energy - amount of energy needed by a charge to move in an electric field
• Far charges repel but has a larger electric potential energy
• Near charges attract but has a smaller electric potential energy
• Electric Potential Energy - effects of the electric field of a source charge at a certain position
• Electric Potential Energy - amount of energy needed for a test charge to move against the electric field of a source charge
• Electric Flux - electric field lines of a uniform field crossing an Area A that is perpendicular to the field
• Electric Flux - quantifies the flow of electric field through a surface
• Electric flux happens in 3D and 2D objects
• Potential Difference - amount of work needed to move a charge from position A to position B
• Voltmeter: measures the potential difference
• Ohmmeter: measures the resistance
• Ammeter: measures the current
• Capacitance - a property of an electrical system that describes its ability to store charge
• Capacitance - denoted by the symbol "C" and is measured in Farads
• Capacitance is directly proportional to the charge
• capacitance is inversely proportional to the voltage
