Building Utilities 1 - Self-regulated Learning Module

Evaluates problem-solving tasks based on completeness, correctness, and principles used.

Assesses the quality of explanations on concepts and principles in process questions.

Course content includes understanding, interpretation, and design of electrical systems

Calculating electrical demands for buildings according to building codes.

Designing residential buildings accounting for electrical and lighting standards.

Electricity is the flow of electrons through a conductor, providing energy for various applications.

Voltage is the electrical potential difference between two points, driving the flow of electrons.

Current is the rate of flow of electrons through a conductor.

Resistance opposes the flow of electrons in a circuit, controlling the current.

Ohm's Law states the relationship between Voltage, Current, and Resistance: Voltage = Current * Resistance.

Power measures the rate at which electrical energy is consumed or generated, usually expressed in watts (W).

Energy is the ability to do work, measured in kilowatt-hours (kWh).

DC is a type of current that flows in one direction only, like in batteries.

AC is a type of current that flows in both directions, constantly changing, like the electricity in your homes.

An electrical circuit is a closed loop path for the flow of electricity, usually consisting of a power source, load, and conductors.

Online student activities are submitted through Google Classroom by a specified deadline.

Offline student activities are submitted via scanned output to the facilitator's Facebook messenger or via courier services (LBC, JRS, etc.).

Activities need to be submitted by a specific date to avoid deductions.

Submitted documents must be in PDF format and clear for easy reading.

Submitting activities after the deadline results in a score deduction.

A module that covers fundamental concepts of electricity.

Chapter 3 deals with the knowledge of light.

Offline students submit activities at the end of each month.

Offline submissions not made within the timeframe will not be graded and require an explanation for credit.

The rate at which electrical energy is transferred or used. Imagine it like the volume of water flowing through a hose.

Electric power is measured in watts (W). One watt is equal to one joule of energy per second.

Power (P) is calculated by multiplying current (I) and voltage (V). P = I x V

The total amount of electrical energy transferred or used over a period of time. Like the total volume of water that has flowed through a hose.

Energy is the total amount of work done, while power is the rate at which that work is done.

Electric energy is measured in watt-hours (Wh). 1 kWh = 1000 Wh

Energy (Wh) is calculated by multiplying power (P in Watts) by time (t in hours): Wh = P x t

Voltage (V) can be calculated by multiplying current (I) and resistance (R): V = I x R

Finding the amount of electric charge flowing through a circuit. It's calculated by dividing the voltage (V) by the resistance (R).

Determining the electrical potential difference across a circuit element. It's calculated by multiplying the current (I) by the resistance (R).

Determining the opposition to the flow of electric current in a circuit. It's calculated by dividing the voltage (V) by the current (I).

The total amount of electrical work done over a period of time. It's calculated by multiplying the power (P) by the time (t).

The expense for using electricity, calculated by multiplying the electrical energy consumption (kWh) by the cost per kilowatt-hour (kWh).

A unit of electrical energy equal to 1 kilowatt of power used for 1 hour. It's used to measure how much electricity you consume.

The formula for calculating electrical energy is: Electrical Energy = Power x Time. Power is measured in watts (W) and time is measured in hours (hr).

Power represents the rate at which electrical energy is consumed or generated. It's measured in watts (W), where 1 watt equals 1 joule per second.

The cost of electricity is determined by the amount of energy consumed in kilowatt-hours (kWh) multiplied by the price per kWh set by the electric company.

To calculate the energy used by an electric lamp, multiply its power in watts (W) by the time it is used in hours.

To determine the cost of using an electrical appliance, multiply the consumed energy in kilowatt-hours (kWh) by the cost per kWh.

To convert watts (W) to kilowatts (kW), divide the number of watts by 1000.

The power consumption of household appliances can vary widely. A laptop typically uses 65-100 watts, while a mobile phone uses much less.
