Refers to the electrons that move through a conductor.

Process in which electric current is produced from a magnetic field.

Converts mechanical energy to electrical energy by applying the principle of electromagnetic induction.

Uses slip rings that are connected to the ends of the armature that rotates it.

Uses split rings or commutators that are connected to the ends of the armature that rotates it.

Common type of machine that converts electrical energy to mechanical energy.

Generated when the motor coil of the wire rotates in an external magnetic field.

The greater the number of the loops of wire that moves in a magnetic field, the greater the induced voltage.

the strength of the magnetic field where the same coil of wire moves at constant speed is increased, the amount of induced voltage decreases.

The current is produced in a conductor whenever the conductor moves relative to the magnetic field lines.

Lenz's law states that an induced current is always in such a direction that its own magnetic field acts to oppose the effect that created it.

states that a voltage is induced in a circuit whenever relative motion exists between a conductor and magnetic field

What is the relationship between the speed of the relative motion between the coil and the magnet?

What is the back EMF of the motor if the motor is connected to a 220 V power source. The coil of wires of an electric motor has a resistance of 20, operating at a normal speed with a current of 8.5 A.

Electric motor is the reverse of a generator.

In a solenoid, the magnetic flux is equal to the product of the cross-sectional area and the component of magnetic field strength perpendicular to the cross-sectional area

The greater the number of loops of wire that moves in a magnetic field, the greater is the induced voltage.

The resistor is automatically switched out when the flow of current is reduced and switched in when the current increases.

The higher the number of the coiled wire, the greater is the resistance.

The body's ability to maintain constant internal equilibrium by adjusting its physiological processes.

Body system responsible for coordinating the functions of all the organs in the body.

anything that makes u respond

Receive the information and send impulses to the spinal cord or brain.

Relay the information from sensory to motor neuron.

Shorter extension of the cell body that aids for better reception of impulses.

Neurotransmitters are chemicals that help transport the message between neurons.

Conduct impulses from the brain or the spinal cord to muscles or glands throughout the body.

Composed of the axon and the myelin layer.

Part of the brain that coordinates fine muscle movement and balance.

Outermost layer of fibrous sheath of muscles that surrounds the nerve fiber.

Basic cellular unit of the nervous system.

Neurotransmitter that regulates sleep and wake cycles.

Part of the brain that serves as the bridge toward the midbrain

Part of the brain responsible for general levels of lethargy or liveliness

Initiates labor of pregnant women and milk ejection.

Triggers ovulation in females and sperm production in males.

Increases blood sugar levels.
