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 is interposing voltage transformer?
Interphase transformers are utilized as a part of frameworks that have two rectifier frameworks being utilized as a part of parallel. The requirement for the Interphase Transformer is available in light of the fact that when associating rectifiers in parallel, their immediate voltages vary.
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.
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 are the advantages and disadvantages of electrostatic energy?
Advantages of electrostatic energy include its cleanliness as a renewable energy source, its effectiveness in particle separation processes, and its ability to produce high voltages for various applications. Disadvantages include potential hazards due to high voltages, the need for specialized equipment for generation and storage, and limitations in terms of energy density and scalability for large-scale power generation.
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.
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.
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
Why is fuse always placed in the live wire of a circuit?
Purpose of the fuse is to save circuits from the damage due to high current and voltages caused during fault conditions. These faults affects the live wire. So fuses are kept there. Morever other parts such as ground, do not need this protection, since these high voltages gets automatically earthed.
