Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
What is the differences between direct circuit and alternating circuit?
The main difference between direct current (DC) and alternating current (AC) is the direction of the electrical flow. In a direct current circuit, the flow of electrons is in one direction, from the negative terminal to the positive terminal. In an alternating current circuit, the flow of electrons changes direction periodically, typically at a fixed frequency, resulting in an oscillating current flow. AC is widely used for electrical power distribution, while DC is commonly used in batteries, electronic devices, and certain applications like electric vehicles.
Ac vs DC current?
DC (direct current) means the current flows only in one direction. In AC (alternating current), the current changes direction continuously (for example, 50 or 60 cycles per second).
What type of current never changes direction?
DC (direct current).
What is the change in current when frequency changes from 8 khz to 400hz?
That depends on the circuit. For a pure resistive circuit (no inductance and capacitance), the frequency will have no effect on the current.
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.
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.
Compare alternating current with direct current?
Alternating current changes direction on a set frequency such as 50 Hz, 60 Hz or 400 Hz. Direct current always flows in one direction.
How can the frequency with which the direction of a current changes be regulated?

Is DC what the role of freqency?
Direct current (DC) never changes its direction of flow, so it has no frequency.
Why frequency exist in ac but not DC?
the frequency of DC is 0 HzAnother AnswerThe term, 'frequency', describes one complete alternation in both magnitude and direction of an a.c. current. As d.c. changes neither in magnitude or direction, then the term frequency cannot be applied to d.c.
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 current changes direction?
Voltage
A flow of electrons in a definite direction is called?
Current. Direct Current (D.C) if it is steady. Alternating Current (A. C) changes direction at a constant rate. The frequency for North American AC current from the power grid is 60 Hz, or 60 cycles per second. This would result in the direction of current changing 120 times per second.
What is ac energy?
That probably refers to an AC current or an AC voltage. That means that the electrical current is not continuously flowing in one direction, but changes direction all the time - typically at a frequency of 50 or 60 cycles per second in the case of household current. Similar for the voltage.
What is the differences between direct circuit and alternating circuit?

In a direct current circuit, the flow of electrons is in one direction, from the negative terminal to the positive terminal.

AC is widely used for electrical power distribution, while DC is commonly used in batteries, electronic devices, and certain applications like electric vehicles.
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
