Electricity
What are all the drawbacks of Direct current?
Disadvantages of DC: * High power transformation of voltage is less convenient than AC. AC uses a transformer. * DC does not have the natural break in transmission that AC has (zero twice per cycle) and does not switch off as easily * DC does not provide time to synchronous clocks * DC dynamos or generators are less efficient at converting input power to output electricity than AC alternators. That is why altenators with rectifiers are now used in vehicles instead of DC dynamos.
