Which type of current is produced by a wire breaking magnetic field lines and changing the polarity?
An alternating current (AC) is produced when a wire cuts through magnetic field lines and experiences a change in polarity. This phenomenon is known as electromagnetic induction, where the changing magnetic field induces a current in the wire.
What is true about diodes?
Lots of things are true about diodes. There are different types of diodes; their general characteristic is that they have two electrodes (electrical contacts). They conduct current in one direction only.
What is an electric current that periodically changes direction?
An electric current that periodically changes direction is called an alternating current (AC). In AC circuits, the flow of electric charge reverses direction many times per second, typically at a frequency of either 50 or 60 Hz. This is in contrast to a direct current (DC) in which the flow of electric charge remains constant in one direction.
What is the function of an AC transistor in electronic circuits?
An AC transistor in electronic circuits is used to amplify and control the flow of alternating current (AC) signals. It acts as a switch or amplifier to regulate the voltage and current in the circuit, allowing for the manipulation and processing of AC signals for various applications.
What is the definition of impedance in physics and how does it relate to the behavior of electrical circuits?
Impedance in physics is the measure of opposition to the flow of alternating current in an electrical circuit. It includes both resistance and reactance. In electrical circuits, impedance affects the flow of current and voltage, influencing the overall behavior and performance of the circuit.
Which current is having high polarity?
ac(Alternating Current ) has the high polarity.
What is the polarity of a circuit?
The polarity of a circuit is dependent upon the type of circuit. Direct current circuits have one negative pole and one positive pole and they flow in one direction. Alternating current circuits the electron flow reverses because the tow poles alternate between negative and positive.
What does ac stand for in circuits?
alternating current
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 has the author K Y Tang written?
K. Y. Tang has written: 'A method of predicting illumination from light courts' -- subject(s): Lighting 'Alternating-current circuits' -- subject(s): Alternating Electric currents, Alternating current, Electric circuits
What do alternating currents do'?
It is an alternating current that switches its polarity 60 times in a second. 60 Hertz is the frequency that electricity is generated in the U.S.
Do integrated circuits have polarity?
Yes integrated circuits have polarity.
What is prince phillip's full name?
The polarity of a circuit is dependent upon the type of circuit. Direct current circuits have one negative pole and one positive pole and they flow in one direction. Alternating current circuits the electron flow reverses because the tow poles alternate between negative and positive.

Are Transformers used in circuits with Direct Current?
No. Transformers are used in circuits with Alternating Current. Transformers work on the principle of a "changing" magnetic field inducing a current in a conductor, and you don't get that "changing" field with Direct Current.
What are the principle of an alternating current in electronic?
the principle of ac current is that it has 1.it has bipolar polarity 2.its avg power and avg energy can be calculated
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
