Alternating current varies in magnitude, and reverses direction every half-cycle. When the current is drifting in one direction we allocate it a 'positive' direction; when it reverses direction we allocate it a 'negative' direction. So the positive half-cycle refers to its variation in current during its forward or positive direction and the negative half-cycle refers to its variation in current during its reverse or negative direction.
What else can I help you with?
What is meant by alternative current?
Alternating current is more efficinent. It is wireless and more efficient than direct current. And it is safer. Plus Tesla is better than Edison
What is meant by anode and cathode?
Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.
What is meant by DC motor?
Only a DC motor uses direct current, and the reason is that it is the only supply available. There are also plenty of AC motors used when there is an AC supply. DC tends to be used for low-power devices like fans in electronic equipment.
What is convetion current?
Did you mean conventional current or convection current?As this question is in an Electronics category, I will assume that you meant conventional current.Conventional current flow is electrical current flow from positive to negative as defined by conventional practicegoing back to Ben Franklin, etc. Note that this is opposite to electron current flow from negative to positive as defined by the physical movement of electrons in conductors, n type semiconductors, and vacuum tubes. Note that this is the same as hole current flow from positive to negative as defined by the physical movement of holes in p type semiconductors.If by some chance you got the wrong category and did mean convection current; that is cyclic fluid flow driven by a heat differential in a gravitational field. It can happen in any fluid: gas (e.g. air), liquid (e.g. water), or semisolid (e.g. hot rocks of earth's mantle).
What is meant by drift current in diode?
when ever the external voltage is given the movement of charge carriers produce a current i.e drift current
What is meant by alternative current?
Alternating current is more efficinent. It is wireless and more efficient than direct current. And it is safer. Plus Tesla is better than Edison
What is meant by frequency of an alternating current?
The frequency of an alternating current is the number of complete cycles it goes through in one second, measured in hertz (Hz). It determines the rate at which the current changes direction and is a key parameter in electrical systems design, particularly for devices that rely on precise timing or frequency-sensitive components.
What are mean and variance of negative binomial distribution by conclusion?
what is meant by a negative binomial distribution what is meant by a negative binomial distribution
What is meant by anode and cathode?
Anode is positive electrode which attracts the negative anions while cathode is the negative electrode which attracts the positive cations during electrolysis.
What type of number is negative 64 squared?
The question is ambiguous. If you meant negative (64 squared), the value is -4096, which is a negative integer. If, instead, you meant (negative 64) squared, the value is +4096, a positive integer.
What is the purposes of capacitor in the circuit?
Capacitor is a device usually meant for storing electrical charges. Same time alternating current of higher frequency would have an easy path to pass through it and block totally the direct current. These two characteristics are used in designing the electrical circuits whichever is very much in need.
What is meant by transformer action?
everything in the world is mechanically advantage.Answer'Transformer action' describes the process by which a voltage is induced into a secondary winding, due to a changing magnetic flux, created by an alternating current flowing through the primary winding, which links the two windings.
What is meant by DC motor?
Only a DC motor uses direct current, and the reason is that it is the only supply available. There are also plenty of AC motors used when there is an AC supply. DC tends to be used for low-power devices like fans in electronic equipment.
What were positive and negative consequences of a limited national government?
Positive consiquences of limited national government meant that states could not do what they wanted. Negative meant no united goals.
What is meant by the term resistance?
What is meant by the term resistivity?
What is meant by the term fusing current?
Fusing current for a wire is the current at which the wire will act like a fuse (melt).
Integers can be positive or negative true or false?
False - if the sentence is meant to be exhaustive. Integers can be positive or negative OR ZERO.
