An electric power system that supplies power to homes and industries for a sizeable region.

a source with a limited supply that we can mine or extract from the earth, and it’ll eventually run out.

a fuel formed by natural processes, such as anaerobic decomposition of buried dead organisms, these fuels are found in the Earth's crust and contain carbon and hydrogen, which can be burned for energy to create electricity.

an act of harnessing the natures power

the natural movement across land or sea, this power become more common now a days an innovation allows to harvest an electricity by using turbines.

Is produced from organic material and commonly used trough out the world, chlorophyll present in plants captures the sun energy by converting carbon dioxide from the air and water from the ground into carbohydrates through the process of photosynthesis, when the plants burned tit release a carbon dioxide in the atmosphere, the chemical energy is released as heat and can generate electricity with a steam turbine.

The movement or flow of electricity through a conductor.

Overhead or underground power lines that carry electricity through cities and neighborhoods to your home or business.

An electrical safety device consisting of a wire or strip of fusible metal that melts and interrupts the circuit when the current exceeds a preset amperage.

An electrical device or devices that use(s) electric power.

The unit of measurement of the electrical resistance of a material.

An electrical facility where transformers lower high transmission voltages to be distributed to customers.

An incandescent lamp having a hot resistance of 66 ohms is put into a socket that is connected to a 115 V supply. What current flows through the lamp?

A household electric water heater is rated 220 V and 20 amperes. What is the unit's resistance when drawing this amount of current?

a complete conducting path that carries current from a source of electricity to and through some electrical device (load)and back to the source.

made of a single electrical conductor used to carry electricity.

a group or bundle of multiple wires inside a common sheathing.

cables consist of a center conductor, insulation, and shield for use in video or other radio frequency communications circuits.

This material is one that will soften and even melt when exposed to high temperature.

used to make or break an electrical circuit. It is used to ‘on’ or ‘off ’ the supply of electricity to an appliance.

An automatically operated electrical switch designed to protect an electrical circuit from damage caused by excess current from an overload or short circuit.

An octagonal shaped electrical material where the connections or joints of wires are being done.

A rectangular shaped plastic or metallic (PVC) material in which flush type convenience outlet and switch are attached.

Metal box with a blank cover that is installed in an accessible place in a run of conduit to facilitate the pulling in of wires or cables
