What is an Electrical Circuit and what types of energy

What is an Electrical Circuit

→ An electric circuit makes electricity move.

→ It has three essential parts: a generator, a device that uses electricity, and a wire that connects them.

→ An electric circuit is a circle or way that electricity moves in.

→ An electrical system has three main parts.

→ The first part is something that gives power, like a generator or battery.

→ The second part is something that uses power, such as a light bulb or motor.

→ The third part that connects them is usually wired.

→ Understanding how something spins can be simple or difficult, depending on the number of parts it has and how they are assembled.

→ A simple spin has three things: a battery, a switch, and a light bulb.

→ A more complicated spin can have more things like many batteries, switches, resistors, capacitors, and other things.

→ There are two important rules for understanding electricity in buildings.

→ They are called Ohm's Law and Kirchhoff's Laws.

→ These rules explain how voltage, current, and resistance remain constant in an electric circuit.

→ These laws are essential for creating and studying electrical circuits used in various areas like generating power, communication systems, and electronics.

Types of Energy

→ Energy can be classified into various types based on its nature and source. Here are some common types of energy:

→ Kinetic Energy: Energy related to how something moves.

→ Potential Energy: An object has stored energy either because of its position or its physical characteristics.

→ Thermal Energy: Energy from atoms and molecules moving in a substance decides its temperature.

→ Chemical Energy: The energy held in the connections between atoms and molecules.

→ Electrical Energy: Energy when electrons move in a wire.

→ Nuclear Energy: The energy is released from the center of an atom through nuclear reactions.

→ Light Energy: Electromagnetic waves carry energy.

→ They include visible light and other types of radiation.

→ Sound Energy: Electromagnetic waves have energy.

→ They include a light that we can see and other types of radiation.

→ Gravitational Energy: The energy associated with the attraction between two objects due to gravity.

→ Elastic Energy: Energy stored in an object when it is pressed together or pulled apart is called potential energy.

What is an Electrical Energy

→ Electricity is made when charged bits like electrons move around.

→ This is a special power that can change into different shapes, like the power to move or the power to make things hot.

→ Electricity is commonly used to make devices and equipment work.

→ It comes from places like power plants, batteries, and solar panels.

→ Electricity is commonly used to make devices and equipment work.

→ It comes from places like power plants, batteries, and solar panels.

→ We use units called joules or kilowatt-hours (kWh) to measure energy.

→ We must learn about these units to use energy wisely.

Calculation of Electrical Energy

→ To find the total electrical energy, you must know two things: the power of the electrical device and how long it is on.

→ The formula for generating electrical energy is:

Energy = Power x Time

→ We use energy to make our homes and devices function.

→ We measure how much energy we use in a unit called a kilowatt-hour (kWh).

→ Power is how fast we use or create energy.

→ We measure it using kilowatts (kW).

→ Time is how long we spend or create energy, and we measure it using hours (h).

→ "If a machine uses 1 kilowatt (1 kW) of power and operates for 2 hours, how can you sum up the electrical energy consumed using a formula?"

Energy = 1 kW x 2 h = 2 kWh

→ The device used 2 kilowatt-hours of electricity in 2 hours.

→ Joules (J) are for small energy amounts, while kilowatt-hours (kWh) are for larger amounts.

→ The numbering system to measure energy is the same, but the units of measurement are different.
