What else can I help you with?
What is longest High Voltage electric transmission line in the US?
Pacific DC Intertie, a 500KV direct-current power line from The Dalles, Oregon to Los Angeles.
Why ac instead of dc?
ac transmission are used because we easily step up the voltage as per our requirment and also breaker used for ac break the ac current easily bcs of nature of zero current at every cycle but for long distance transmission done by dc due to reducing the skin effect and also reduce the relative inductance of the line due to this the line losses are reduce and we transmit the more power.
Is batteries alternative current or directly current?
Batteries store DC, or Direct Current. The correct term for AC is Alternating Current.
Example of a DC current device?
a typical example of a d.c current device is a generator it supplies current directly to houses
What is DC load line of a transistor?
A: A transistor has voltage gain as base current is allow to flow. If the load is constant then a DC mirror azimuth path can be plotted as a function of base current and collector current and that is the load line
Why you use ac current of home instead of dc?
alternating current is generally instantaneous in nature and even in transmission lines it is easy to transmit with less losses when compared to dc as because it possess frequency where as dc do not have
Why ac prepared DC current?
because the transmission cost of ac supply is lesser than dc. thats why ac is prefered
How many phase are there from transmission line from Oregon?
AC transmission lines are 3-phase, DC transmission lines don't have phases. It doesn't matter where they are from.
What is the difference between current (DC) and alternating current (AC)?
ac comes directly from the power socket, and DC is battery source. Answer2: The frequency is the difference, AC has frequency f>0 and DC does not f=0.
400 kv transmission double circuit dc power line's restricted area?
no it no restricted
Why is not impractical to power distribution in power DC?
IN DC FOR LOW VOLTAGE HIGH DENSITY OF CURRENT WILL BE THERE SO WE CAN NOT USE THIS FOR BEST PRACTICE FOR TRANSMISSION & ALSO BECOS OF HIGH CURRENT TRANSMISSION LOSSES ARE VERY HIGH ( I2XR) LOSSES, TRANSMISSIN EQUIPMENT FOR DC ARE HIGH COSTIN DC FOR LOW VOLTAGE HIGH DENSITY OF CURRENT WILL BE THERE SO WE CAN NOT USE THIS FOR BEST PRACTICE FOR TRANSMISSION & ALSO BECOS OF HIGH CURRENT TRANSMISSION LOSSES ARE VERY HIGH ( I2XR) LOSSES, TRANSMISSIN EQUIPMENT FOR DC ARE HIGH COSTAnswerThe main reason is that we cannot use transformers to easily and efficiently change the magnitude of DC voltages, and the ability to change voltages is essential for electricity distribution. However, having said that, very high-voltage transmission over exceptionally long distances is often done using DC. This is because DC losses are far lower than AC losses.
Why ac current is more dangerous than dc?
no actually dc current is more dangerous than ac because dc is a direct current and has no current zero condition ,which is very dangerous and do not leave us if we get shock while ac current leave us when we get shock
