What are the reasons for generating energy as alternating current?
ENERGY CAN BE GENERATED ONLY AS A ALTERNATIG CURRENT.THERE IS NO WAYS OF GENERATING ENERGY AS A DC DIRECTY.IN CASE OF DC GENERATION ,AC IS GENERATED FIRST AND THEN RECTIFIED INTO DC. TO UNDERSTAND THIS CLEARLY YOU NEED TO KNOW THE WORKING OF GENERATORS. THE REASONS FOR GENERATING ENERGY AS AC IS ENERGY CANNOT BE GENERATED AS DC.
Why ac transmission voltage is 765 kv?
For a given load, the higher the supply voltage, the lower the resulting load current. So high voltages are essential for electricity transmission, in order to avoid enormous voltage drops, a need for conductors for huge cross-sectional areas, and to reduce line losses. Actual transmission sytem voltages are determined by the electricity-supply standards used in the country in which you live.
Why do some electronic circuits need negative voltages?
Because , in some cases for a negative voltage the circuit components will be biased .
How do i convert from 380 volts to 220 volts?
If these are the exact voltages that you need you will need an auto transformer to obtain these voltages. If these voltages are nominal voltages and are of a three phase four wire configuration, the 220 voltage can be obtained from the three phase legs to the neutral (ground) connection. The equation to use is 400/1.73 = 231 volts.
What if surge protector had high resistance?
If a surge protector had a very high resistance at all voltages, the wires in the surge protector would short out. It would kick off the protector and make it useless. A new surge protector would need to be purchased.
Need for generating high voltages in laboratory?
because in laboratory almost we are using only three phase equipents,so we require more pewer in laboratory, thats why we are generating high voltage in laboratory.
What do you have to use to see the fine details of a cell's surface?
You would need an extremely high-powered microscope to see the fine details. For this high powered of a microscope, it would only be found in laboratories
Why alternating current is use for electrical system?
The transmission of electrical energy requires very high voltages (for a given load, the higher the supply voltage, the lower the load current). To increase/reduce these voltages, you need transformers. Transformers are AC machines; they do not work with DC.
Why do we need hazard warning signs in laboratories?
because of safety
What is a generating market?
a group of buyers have a same need..............
What is the voltage need for fluorescence lamp?
Fluorescent fixtures can be used with a variety of voltages.
How do i wire a Dual voltage motor with 120?
Need to know what the dual voltages of the motor are.
HOw does electricity get transported and why does it need to be at a high voltage?
The primary reason that power is transmitted at high voltages is to increase efficiency. ... The higher the voltage, the lower the current. The lower the current, the lower the resistance losses in the conductors. And when resistance losses are low, energy losses are low also.

Why do you need communication in science laboratories?
because if something goes wrong other scientists need to know what to do whether it is to get out or clean it up
Which circumstance would the use of an antistatic wrist strap be discouraged?
Anti-static straps are used to prevent damage to electronic components when being handled by assemblers or engineers. They work by dissipating voltages to ground and prevent a build up of static voltage. They should not be used when high voltages may be present on the assembly or near the assembly as the grounding strap can cause excess current to pass through the operative. Where high voltage devices need protection against static voltages, special grounding straps and grounding techniques can be used to provide protection to the circuit without becoming a hazard to the the operator.
Where would microscopes be used?
Wherever people need to look at really small things, usually in laboratories.
