read more An electron is a fundamental, negatively charged particle within an atom, while electricity is the flow or movement of these electrons (or other charges) through a conductive material, like a wire, which we harness as electric current. Think of electrons as individual marbles and electricity as the wave or chain reaction when you push one marble, making the whole line move, with the energy transferring quickly, even if individual marbles don't travel far. Energy is the capacity to do work (measured in Joules or kilowatt-hours), while power is the rate at which that work is done or energy is used (measured in Watts or kilowatts). read less

Unit of energy: Joule (J) or kilowatt-hour (kWh) Example: A charged battery has energy. Electricity bill is based on energy used (kWh). Power is the rate at which energy is used (how fast energy is consumed). Unit of power: Watt (W) Formula: \text{Power} = \frac{\text{Energy}}{\text{Time}} Example: A 100 W bulb uses energy faster than a 40 W bulb. Power is the rate at which energy is used (how fast energy is consumed).

read more What is an Electron? An electron is a very tiny particle found inside every atom. It has a negative charge (–) It is extremely small It moves around the nucleus of an atom 👉 Easy way to remember: Electrons are like tiny ants moving inside all materials. 2️⃣ What is Electricity? Electricity is the flow of electrons. When electrons move, electricity is produced When electrons don’t move, there is no electricity 📌 Example: Battery connected to a bulb → electrons start moving → bulb glows 💡 Switch OFF → electrons stop → bulb goes off 👉 One-line definition: Electricity = movement of electrons 4️⃣ What is Energy? Energy is the ability to do work. Makes things move Makes bulbs glow Makes fans rotate 📌 Examples of energy: Food → gives body energy Battery → stores electrical energy Electricity → a form of energy 👉 Unit of energy: Joule (J) or kilowatt-hour (kWh) 5️⃣ What is Power? Power tells us how fast energy is used. More power = energy used quickly Less power = energy used slowly 📌 Example: 100 W bulb uses energy faster than 40 W bulb 👉 Unit of power: Watt (W) read less

Electricity: The directed movement or flow of these free electrons through a conductor, like a wire, driven by a force (voltage). Energy: The ability to do work, like lighting a bulb or heating a room. Electrical energy is the energy from moving charges and can be stored (batteries) or converted (heat, light). Energy (E): The total work done or total energy consumed.Formula: Energy = Power × Time (\(E=P\times t\)).Units: Joules (J), Watt-hours (Wh), or kilowatt-hours (kWh). Power (P): The rate at which energy is used or transferred (Energy per unit time).Formula: Power = Energy / Time (\(P=E/t\)). Units: Watts (W) or Joules per second (J/s). read less

read more The Electron and Electricity Electron: A subatomic particle that carries a negative electric charge. In certain materials like metals (conductors), some electrons are "free" to move from one atom to another. Electricity: The general term for the presence or flow of these electric charges. Current Electricity: When a force (called Voltage) is applied, it pushes these free electrons to flow in a specific direction through a wire. Static Electricity: When electric charges build up and remain in one place rather than flowing. Energy is the total capacity to do work. It represents an amount that can be stored and used over time. Power is the rate at which energy is used or transferred. It describes how fast work is being done at any given moment. read less
