Residential Wiring Practice Questions with
Correct Verified Solutions
What are the two basic forms of energy?
kinetic energy and potential energy
What is the formula for determining energy efficiency?
n=Eo/Ei x100%
What is a transformer?
An electrical device that uses electromagnetism to change (step up or step down) AC voltage
from one level to another
What is distributed power generation?
The generation of power on site or in close proximity to where the power is used
What is interactive distributed generation?
On site power generation where switchgear can activate additional generation sources on demand
What is a micro grid?
A small local electrical network or grid that can operate completely separate from the main
electrical grid
What is a smart grid?
An electrical grid in which electricity is delivered and monitored from a power source to an end
user
, Traditionally, residences have only been wired for what type of current?
AC
What is a smart home?
A residence that contains equipment, appliances, and software that are designed to provide
security, energy management, and convenience
What is a hybrid AC/DC micro grid?
A localized electrical grid or network that operates on AC/DC and can be disconnected from the
traditional electric grid or smart grid to operate on its own power source
What are the benefits of direct DC connection?
More efficient for powering electronic devices because an adapter is not required.
A direct DC connection eliminates the energy loss from DC to AC and AC to DC conversion.
What are the three main sources of renewable energy?
Sun, wind, and water
What are the other sources of renewable energy?
Solar thermal and geothermal energy
Where does geothermal energy come from?
heat within the earth
What is a heat pump?
