Let's see an example. A current does a complete cycle every 0.02 seconds - that is, if at one moment it is at maximum, 0.02 seconds later, it will be at maximum again. You might also say that it has 50 cycles per second.
In this case, the period is 0.02 seconds; the reciprocal is the frequency (50 Hz in this case).
What else can I help you with?
The periodic time of an alternating-current system is the?
The periodic time of an alternating-current system is the is the time in seconds that has to elapse before the waveform repeats itself from its beginning to the end. It is denoted as the Period (T).
A current that charges direction and intensity at a regular interval of time is called?
alternating current (AC)
The periodic time of an alternating current system is?
The reciprocal of the frequency, so a 50 Hz system has a period of 1/50 seconds.
When electrons flow in one direction what is that called?
The electrons flows from negative to positive and then positive to negative.The pole of the flow of electron changes at a time interval.This is called alternating current (AC).
What is a frequency of ac signal in Pakistan?
The current which changes it direction after every half cycle is called alternating current(A.C) or Alternating current which produced by voltage source whose polarity keeps on reversing with time. By Shahnam qadeer
Define alternating current definition?
The alternating current refers to the flow of the electric charge periodically and in the opposite direction. The polarity changes with the time..
What is AC periodic wave?
An AC periodic wave refers to an alternating current waveform that repeatedly varies with time, switching direction at regular intervals. This type of wave is commonly used in electrical systems to generate power and transmit signals. AC periodic waves are defined by their amplitude, frequency, and phase characteristics.
Where did Nikola Tesla invent the alternating current?
He was living in New York at the time.
What is direct current and alternating current?
Direct current is a constant, steady state current, such as obtained from a battery. Alternating current is constantly switching polarity, usually in a sinusoidal waveform, such as obtained from an alternator, a form of generator that does not have a commutator.Direct Current and Alternating Current:The first and simpler type of electricity is called direct current, abbreviated "DC". This is the type of electricity that is produced by batteries, static, and lightning. A voltage is created, and possibly stored, until a circuit is completed. When it is, the current flows directly, in one direction. In the circuit, the current flows at a specific, constant voltage (this is oversimplified somewhat but good enough for our needs.)The other type of electricity is called alternating current, or "AC". This is the electricity that you get from your house's wall and that you use to power most of your electrical appliances. Alternating current is harder to explain than direct current. The electricity is not provided as a single, constant voltage, but rather as a sinusoidal (sine) wave that over time starts at zero, increases to a maximum value, then decreases to a minimum value, and repeats.
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).
What does the term frequency mean in electricity?
That refers to AC (alternating current). A direct current flows only in one direction; an alternating current changes its direction all the time. The "frequency" refers to how often the current changes direction. It is expressed in hertz (Hz), which means the same as cycles/second.
Is the lightning is alternating or direct current?
i think it is ac. bcs the direction is changed with time. so it is ac
