What do electrical engineer's do?
EE is a vary broad discipline. EEs design circuit boards, design and code software, design communication systems (wireless and wired), design antennas, design computers, design EM (electromagnetic) components.... the list goes on and on.
What are photovoltaic systems used for?
Photovoltaics means to generate electricity from sunlight. Tiny photovoltaic cells are used in devices such as calculators, to save battery power. Larger systems are used to provide electricity to devices or homes that are far from the interconnected electric network.
What is the common household electrical service is usually rated at phase?
The common household electrical service is usually rated as a single phase service. In North America there are a few 120/208 three phase services being put into larger homes.
What is transformers necessity?
Outside the homes, electricity is transferred at several thousand volts, for reasons of efficiency (less energy is wasted that way). This voltage is far too high for home use. (Also, home devices are set up for a specific voltage.)Outside the homes, electricity is transferred at several thousand volts, for reasons of efficiency (less energy is wasted that way).

Why don't you power your homes with fruity batteries?
-- The electrical devices that we've become accustomed to using in our homes need much more power than any reasonable amount of fruit can deliver. -- The electrical devices that we've become accustomed to using in our homes operate on AC, whereas fruit delivers DC. -- When you take into account the energy and other resources required to plant, grow, harvest, distribute, install, operate, and maintain fruit, it isn't that much of a bargain compared to the current methods of mass producing electrical energy. -- The whole notion of turning food into fuel for cars, TVs and washing machines is demented.
How electrical energy can be conserved in homes?
By turning off lights or other devices you don't use and by installing energy-saving equipment (especially lights).

What all uses electricity?
electricity is used in factories, industries. we require electricity at our homes for TV. , mixers etc . we need electricity for the electrical devices in hospitals. we are dependent on electricity for almost all our activities throughout the day
How can electrical appliances be operated in areas where an electricity supply is not really available?
You will have to use battery powered devices or have a generator to produce electricity. More recently a large number of homes have solar energy from the sun which generates electricity
What do the outlets in your homes provide?
The outlets in your home provide the convenience to be able to use electricity at specific points in rooms throughout the house. This saves not have to take your equipment to the distribution point where the power enters the building to operate the equipment.
Is the electric circuit in your home a series circuit or parallel circuit?
In my home, all of the utility outlets and all of the AC electrical devices we use arein parallel with all the others, and also with all similar outlets and devices in all ofthe homes of all of our neighbors whose houses are on the same transformer.
