: This seems like a question from an electrical course, and is probably best answered by your course materials. : It's your test question, not ours, and there won't always be someone else to ask for the answer. Earn your diploma.

What is the hyperbola's point halfway between its two vertices?
Center
Every point on a circle is the same distance from what location?
The points are all the same distance from the center of the circle. The distance between the center and any point is the radius of the circle.
Does an octagon have a center point?
Yes, an Octagon does have a center point. The easiest way for me to find this is by drawing lines between opposite vertexes. You should end up with four lines and they should be crossing at one point. That is your center point! :V
What is the difference between a circle to an oval?
circle has single center point and is equidistant to point of radius,while oval has four(4) center points with two(2) different radius.

How does an electric utility ground electricity delivered to your home?
Electricity is delivered to homes through transformers. The center of the transformer output winding is connected to ground. This center tap is then connected to the home power panel as the neutral lead. The voltage between the grounded neutral and either of the "hot" legs is half the voltage between the legs. In the US and Canada, the full voltage between the legs is 240V and between either leg and neutral is 120V.
Explain the working principle of center Tapped transformer full wave rectifier?
Explain the working principle of center Tapped transformer full wave rectifier? A center tapped transformer full wave rectifier is a type of rectifier circuit that converts alternating current (AC) to direct current (DC) using a transformer and diodes. The working principle of this circuit is based on the use of a center tapped transformer. A center tapped transformer is a transformer with a secondary winding that has a center tap, which is connected to ground. The primary winding of the transformer is connected to the AC source, and the secondary winding is connected to the load resistor and the diodes. During the positive half-cycle of the input AC voltage, the upper end of the secondary winding is positive with respect to the center tap, and the diode connected to this end conducts. At the same time, the lower end of the secondary winding is negative with respect to the center tap, and the diode connected to this end is reverse-biased and does not conduct. The current flows through the load resistor in the direction of the arrow. During the negative half-cycle of the input AC voltage, the lower end of the secondary winding is positive with respect to the center tap, and the diode connected to this end conducts. At the same time, the upper end of the secondary winding is negative with respect to the center tap, and the diode connected to this end is reverse-biased and does not conduct. The current flows through the load resistor in the opposite direction of the arrow. As a result, the output voltage across the load resistor is a pulsating DC voltage that alternates between positive and negative values but has a DC component. The ripple voltage of the output is lower than that of a half-wave rectifier since it rectifies both half-cycles of the AC input voltage. The advantage of using a center tapped transformer in a full-wave rectifier circuit is that it allows the output voltage to be double the voltage of a half-wave rectifier using the same transformer.
How many diodes can be used in center tap type rectifiers?
There are two diodes in a standard center tapped configuration of a rectifier. This is per phase, so if you had a three phase system, each winding having a center tap, all of which are connected together, you would have six diodes.
What is extension c holder?
An Extension Cord Holder having side members connected by a center section which is shorter than the side members so as to provide a cord receiving space therebetween at opposite ends of the center section, the center section preferably has curved ends to facilitate the winding of the extension cord about the center section, and a handle is connected to one side member for carrying the Extension Cord Holder.
Difference between a bipolar and unipolar stepper motor?
There are two different winding configurations for stepper motors. A unipolar stepper motor has one winding coil and a center tap which is activated for proper frequency. The bipolar stepper motor is more complex since the winding motion must be reversed to get the proper frequency.
We are using neutral wire for electrical technology and ground wire for electronic devices and circuits what is the difference between them?
The "neutral" wire gets it's name from the fact that it is the "center tap" of a feed transformer. A transformer has a primary winding and a secondary winding. The utility company provides high voltage to the primary winding of the transformer that is outside your home somewhere. It's usually close; withing a hundred yards or so. The secondary winding outputs 240 Volts, which is then fed into most homes. The secondary winding is divided into two halves, with a "center tap" between the two. Each half of the 240 Volts shares a "common" wire which is, coincidentally called, the neutral. The ground wire is used to provide protection to people and circuits. Since the neutral often "floats", it cannot be used as the ground, and a separate ground wire is connected to a rod that is driven deep into the... ground. Hope that helped clear things up.
What is center tap transformer?
