why induced EMF is known as back EMF​

Answers

Answer 1

Answer:

Induced EMF is also called back EMF because, the induced EMF opposes the change in current, due to the source of EMF. The induced current causes a restoring torque in the coil. An external source is responsible for the supply of energy for this torque. So we can say that source of this power is the external rotor.

Answer 2
In electromagnetism and electronics, electromotive force, is the electrical action produced by a non-electrical source. Devices provide an emf by converting other forms of energy into electrical energy, such as batteries or generators. Sometimes an analogy to water pressure is used to describe electromotive force.

This patient is a 48-year-old white male complaining of a history of petechial lesions on the bilateral lower extremities and a 2 week history of swelling and pain in the right ankle. He denies any history of trauma, bites, tick exposure, or new medications. Additional findings are significant for submucosal hemorrhage of the oral mucosa gingival hypertrophy with bleeding gums.

Answers

Answer:

Petechiae are elementary lesions, where they are considered red spots without relief due to blood extravasation, where the blood spills to the extravascular environment.

On the other hand, this phenomenon usually occurs in gums and skin when the condition is systemic and not due to a local phenomenon.

Explanation:

Petechiae can occur due to diseases such as scurvy, which is a deficiency of vitamin C which generates capillary fragility due to alteration of collagen formation.

Chronic administration of corticosteroids in the long term, thus generating fragility of the capillary wall.

Or finally, it could become a malignant disease such as leukemia or kaposi's sarcoma, where cell metaplasia generates these lesions accompanied by spontaneous hemorrhages in the oral mucosa.

Which of the following areas of the brain influence addiction?
The limbic system
The reward pathway
Neurotransmitters
All of the above

Answers

The answer is :The reward pathway

Answer:

the answer is All of the above

Addiction refers to a brain disorder characterized by a compulsive engagement in rewarding stimuli despite bad consequences.

Neurotransmitters are chemical messengers used by the nervous system to transmit messages between neurons. Neurotransmitters are strongly associated with addictive behaviors because the brain changes the production of these substances in response to certain drugs and/or stimuli. Moreover, drugs may alter interfere with the mode in which a neuron sends and processes signals through neurotransmitters. For example, marijuana is able to activate neurons by mimicking neurotransmitters. Moreover, dopamine is a neurotransmitter that is released in response to drugs, thereby showing a pleasure/reward effect.

The limbic system is a set of brain structures located within the cerebrum of the brain (below the temporal lobes), which is involved in controlling emotional behaviors. Drugs interact with the limbic system to release intense good emotions that affect the individual's body and mind.

The reward pathway, also known as the mesolimbic pathway, is located within the mid-brain and is a part of the limbic system. The reward pathway is recognized to play a role in drug addiction by acting as a detector of rewarding stimuli. In this regard, it has been shown that dopamine is the most important neurotransmitter in the reward pathway in addiction.

Therefore, all these components and structures of the brain are involved in addictive behaviors
