AC is used for transmission because AC can be stepped up in voltage with a transformer, and then stepped back down at the destination. Since power is voltage times current, a higher voltage requires a smaller current to achieve the same power. Since the current carrying capacity of wires is based on wire size, a smaller wire size can be used to transmit the lower current.

Does having a transmission affect the ac?
Yes, having a transmission can affect the operation of an air conditioning (AC) system, particularly in vehicles. The transmission can influence engine performance and, consequently, the power available for running the AC compressor. In some cases, if the transmission is malfunctioning, it may lead to reduced engine efficiency, impacting the AC's cooling performance. However, in standalone home AC systems, the transmission is not a factor, as they operate independently of vehicle mechanics.
Do trains use ac or dc elecricity in the UK?
train uses acpower as its source.as in case of dc there would be only steady state conditions and transmission distance would be low.but in ac,it is sinusoidal waveform and transmission of power source can be done at a larger rate with high effeciency and minimal lose.so ac source is used in electric trains.
What is the difference between in ac and dc powwer cable?
There is no difference in the cables. The only difference is the type of electrical power being transmitted. AC or DC applications use the same wires.
Advantages of flexible ac transmission system?
1. Very high power transfer capability. 2. Very high controllability.
What two reasons may justify the use of AC?
The use of alternating current (AC) can be justified for two main reasons: first, AC can be easily transformed to different voltages using transformers, making it efficient for long-distance transmission with reduced energy loss. Second, AC motors and devices are generally simpler and more cost-effective to manufacture and maintain compared to their direct current (DC) counterparts, which enhances their widespread application in various industries.
why do transformers use alternating current?
Transformers use alternating current (AC) for several reasons: Easier Transformation: AC voltage can be easily stepped up or down using transformers, making it ideal for power transmission and distribution. Efficient Transmission: AC reduces energy loss during transmission due to the ability to use higher voltages and lower currents. Simple Generation: AC is easily generated using rotating machinery (e.g., generators). Polyphase Capability: AC enables the use of polyphase systems, which increase power transmission efficiency and reduce wire requirements. Economical: AC transformers are less expensive and more compact than direct current (DC) transformers. AC's changing polarity allows the magnetic field in the transformer to induce voltage in the secondary coil, enabling efficient voltage transformation.
Why do transmission lines use alternating current instead of direct current?
Transmission lines use alternating current (AC) instead of direct current (DC) because AC can travel long distances with less energy loss. AC can be easily converted to higher or lower voltages using transformers, which is important for efficient power distribution. Additionally, AC allows for easier control and regulation of power flow in the grid.
Who is better ac or DC transmission?
ac transmission is better. because it is cheaper as converter are not use.but losses are more as comparison to dc.

Why is AC better than DC in terms of electrical power transmission?
AC is better than DC for electrical power transmission because it can be easily converted to different voltages using transformers, allowing for efficient long-distance transmission with minimal power loss. Additionally, AC can be easily generated and distributed in power grids, making it more practical for widespread use.
Why is AC better than DC in terms of power transmission and distribution?
AC is better than DC for power transmission and distribution because it can be easily converted to different voltages using transformers, allowing for efficient long-distance transmission with minimal power loss. Additionally, AC can be easily generated and distributed in large power grids, making it more practical and cost-effective for widespread use.
Where is the highest transmission voltage in India?
the highest transmission volatage in India is 765kV ac. The highest voltage in the case of DC transmission is +/- 600 kV.
Why ac prepared DC current?
because the transmission cost of ac supply is lesser than dc. thats why ac is prefered

What year transmission do I have in my Ford Mustang numbers are F4zr-7003-ac?
It is a 94 Mustang Transmission
What are the advantages of powering a city with ac rather than dc?
There are actually several downsides to AC rather than DC, but there's one overwhelming advantage that means we use it anyway: transmission losses are lower.
Why do you use alternating current in your homes rather than direct current?
Electronic appliances in our homes use dc to operate however externally they are connected to ac source because their internal circuit already contains rectifier. we use ac in our home due to: 1.safety:dc is dangerous then ac. 2.cost:appliances or material required in transmission of dc is costly
