What is the direction of the current?
Current flows from negative to positive for DC. AC the direction changes with the sinewave. eg. AC a frequency of 60Hz the direction changes 120 times.
Battery ac or DC?
A battery supplies DC.
Can hertz kill?
The meaning of Hertz is a unit of frequency in SI; a high frequency electrical current can kill.
What is true regarding DC current?
A DC current flows only in one direction.
Is a 9 volt battery ac or DC?
All Batteries are DC or Direct Current.
Does dc have hertz?
No.
Electrically how is AC different from DC current?
DC is direct current, current travels in one direction. AC is alternating current, current changes direction twice per cycle. 60 Hertz would change direction 120 times per second.
What is ac and what is DC?
DC stands for "direct current", AC for "alternating current". A direct current flows in a single direction; an alternating current changes its direction all the time, typicall 100 or 120 times a second (twice the frequency, which is measured in hertz).
Why do you not consider frequency in direct current?
Although DC current can vary in voltage and current over time, it does not reverse polarity, which in AC occurs some distinct number of times per second (hertz) which is the frequency.
What measurement can vary with AC current by not DC current?
HZ. Hertz is the name given to the frequency of the alternating circuit. Direct current (DC) has no frequency since one wire is always positive and the other is always negative; but AC (Alternating Current) rapidly changes polarity, and does so at a rate that is defined by HZ.
What is the direction of the current?
Current flows from negative to positive for DC. AC the direction changes with the sinewave. eg. AC a frequency of 60Hz the direction changes 120 times.
What are hertz described as?
Hertz is the term meaning cycles per second. Household current in the US is 60 hertz.
What is frequence of dc supply?
Zero = Nothing = Nil = 0 Hertz or Cycles per Second Direct Current is just as its name says: it does not alternate so it does not have any "frequency".
How DC generator produces DC current from ac current?
DC GERATORS PRODUCE DC current with the help of spilt ring commutators.
What device converts dc current to ac current?
A "Rectifier" converts AC current to pulsating DC current.
Battery ac or DC?
A battery supplies DC.
Can hertz kill?
The meaning of Hertz is a unit of frequency in SI; a high frequency electrical current can kill.
