Key Points of Electrical Fundamental By AviAtor SuNiL BhaBar
General Composition of Matter
• Matter: Any object that has mass and volume. It can be in liquid, solid or gaseous form.
• Elements: Any object which can not be reduced to a simpler form (only one type atom) by chemical means (e.g., iron, silver, oxygen, gold).
• Compounds: Substances made of two or more different elements chemically bonded together in fixed proportions (e.g., water, H₂O).
• Molecules: The smallest units of compounds or elements that retain their chemical properties. They consist of two or more atoms bonded together (e.g., O₂, CO₂).
• Atoms: The smallest units of an element that retain its chemical properties. They are made of protons (+ve), neutrons (neutral), and electrons (-ve).
Electron Movement's
• Conductor: material that allows free movement of electrons, enabling the easy flow of electric current (e.g., copper, silver).
• Insulator: material that resists the flow of electrons, preventing electric current from passing through (e.g., rubber, glass).
• Semiconductor: materials which have a electrical conductivity between the characteristics of conductors and insulatorsl (e.g., silicon, germanium).
• Capacitor: A instruments that can store energy in the form of electric charge. It is measured in farads (F).
• Electric Circuit: A closed path through which current flows.
• Direct Current (DC): Electric Current that flows in one constant direction.
• Alternating Current (AC): Electric current whose direction changes time to time (periodically).
• Resistor: A component that limits or regulates current flow in a circuit.
• Series Circuit: In Ckt Components connected same path, so current flows same and voltage will be divides.
• Parallel Circuit: In Clt Components connected two or three or more paths; so current divides and voltage will be same.
• Voltage (V): The electrical potential difference between two points, driving electron flow; measured in volts (V).
• Current (I): The rate of flow of electric charge (electrons) through a conductor. It is measured in amperes (A).
• Power (P): Rate of energy transfer, measured in watts (W); P=VI
• Resistance (R): The opposition to the flow of electric current in a material; measured in ohms (Ω).
• Inductor: Stores energy in a magnetic field when current flows, measured in henries (H).
• Electric Field: The area around where the electric charge is applied.
• Magnetic Field: The area around a magnetic substance or a moving electric charge within which the magnetomotive force acts.
• Electromotive Force (EMF): Voltage generated by a battery or generator.
• Coulomb: Unit of electric charge; (1 coulomb = 6.24 × 10¹⁸e-).
Instruments
• Ohmmeter: Instrument for measuring resistance.
• Ammeter: Instrument for measuring current.
• Voltmeter: Instrument for measuring voltage.
Batteries
• Primary Cell: A non-rechargeable battery that provides electrical energy through an irreversible chemical reaction (e.g., alkaline battery).
• Secondary Cell: A rechargeable battery that can be recharged by reversing the chemical reaction through an external power source (e.g., lithium-ion battery).
Laws
• Ohm’s Law: 𝑉=𝐼𝑅
V=IR; relationship between voltage, current, and resistance.
• Faraday’s Law: Describes how changing magnetic fields induce electric current.
• Kirchhoff’s Current Law (KCL): The Total current entering a junction equals the total current leaving the same junction.
• Kirchhoff’s Voltage Law (KVL): The sum of all voltage's around a loop = zero.
