What Is the Frequency in Hertz (Hz) of the Current

question 24

Short Answer

What is the frequency in hertz (Hz) of the current furnished by an alternator having 8 poles and running at a speed of 900 revolutions per minute? $$\begin{aligned}f = \frac { P N } { 60 } \quad \text { where } & f = \text { frequency in hertz } \\P & = \text { number of pairs of poles } \\N & = \text { revolution per minute }\end{aligned}$$

Definitions:

Presynaptic Terminal

The end portion of an axon, responsible for releasing neurotransmitters into the synaptic cleft to communicate with a neighboring neuron's dendrite.

Sarcolemma

The cell membrane of a muscle fiber that encloses its cytoplasm and helps transmit action potentials.

Neuromuscular Junction

The neuromuscular junction is the site where a nerve fiber connects to a muscle cell, facilitating the transmission of electrical impulses that prompt muscle contraction.

Synaptic Vesicles

Membrane-bound sacs in the synapse, storing neurotransmitters that are released during neural communication.
