Difference between back EMF and induced EMF?
An induced electromotive force (emf) is an induced voltage. Voltage (emf) causes current flow, and this induced voltage will cause a current that is called the induced current.We might also add that the induced current will cause a magnetic field to expand about the current path, and this field will "sweep" the conductor. The sweeping of the conductor by that expanding magnetic field will set up an emf that will oppose the emf that was creating it.CommentTechnically, there is no such thing as an 'induced current'. It is voltage that is induced. Any current flows as a result of that induced voltage being applied to a load. But that current is certainly NOT induced!
What is self induced?
When a current in a coil increases or decreases, there is a change in magnetic flux linking the coil,an e.m.f. is induced. This is called self induced e.m.f. and the process is called self induction.
What determines whether an induced current is a direct current or an alternating current?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
Why voltage induced when moving coil cuts flux?
The magnetic flux passing the coil changes by its rotation thus induced emf is produced and induced current flows
What is induction of electric current?
According to Farady's law, whenever the flux linking with the coil changes, emf will induce in that coil.Actually the material should oppose the flux changes, that opposition is the induced current. Induced current will set own flux, opposite to that of the flux changes.For further details, refer lenz law.
The concept of aggression cues is associated with?
frustration-aggression theory
According to the frustration-aggression principle the immediate response to frustration is aggression depression resignation or anger?
According to the frustration-aggression principle, the immediate response to frustration is anger. This theory suggests that when individuals are blocked from achieving a goal or desire, they are more likely to feel and express anger as a response.
Is frustration linked to aggression?
Yes, frustration can be linked to aggression as it often leads to feelings of annoyance and anger, which can manifest as aggressive behavior when not properly managed. However, not all acts of aggression stem from frustration, as there are various other factors that can contribute to aggressive tendencies.
What is frustration-agression hypothesis?
The frustration-aggression hypothsis is an attempt to state a relationship believed to be important in many different fields of research. It is intended to suggest to the student of human nature that when he sees aggression he should turn a suspicious eye on possibilities that the organism or group is confronted with frustration; and that when he views interference with the individual or group habits, he should be on the look out for, among other things, aggression.
The most serious problem with aggression is that-?
we aim it at people or things that are not the cause of our frustration.
Choose the scenario that best shows how to deal with aggression resulting from frustration?
C
What is prejudice frustration-aggression?
The frustration/aggression theory states that frustration will lead to aggression If people have difficult living conditions (for example) but have no reasonable target to blame this frustration on, they displace their aggression onto another group/target. Such a target is usually weaker/more vulnerable. Related study: Hovland and Sears (1940) - negative correlation between the number of lynchings of black people and the price of cotton
What is frustrated induced criminality?
Frustration-induced criminality is when a behavior directed at a specific goal is blocked, arousal increases, and the person experiences a drive to reduce it.
The condition of being prevented from reaching a goal by event that are beyond your control is?
frustration that willlead to aggression
Can anxiety cause abusive relationships?
Most certainly yes. Anxiety > frustration > aggression > abuse.
What is an adjective for frustration?
The typical adjectives are the participles: frustrated and frustrating, depending on whether the frustation is felt or induced.
Testing the hypothesis that frustration encourages aggression would require?
conducting a research study where participants are exposed to frustrating situations and then their levels of aggression are measured. The study should include control groups to compare results and statistical analyses to determine if there is a significant relationship between frustration and aggression. Ethical considerations must also be taken into account when designing and conducting the study.
