### What does the field strength say?

There is one in the space around a charge electrical Field. This electrical Field transfers the force of this charge to other charges. The electric field strength is Are defined than the quotient from the electrical Force → Fel on a test charge and the test charge q: → E = → Felq.

### What is electrical polarization?

polarization (Electricity) polarization (or dielectric polarization) means a charge shift in a non-conductive material. This is done by applying an outer one electrical Field. The charge shift in a conductor, on the other hand, is called influence.

### How does a capacitor work?

A capacitor is is an electrical component used to store electrical charge and thus electrical energy. ... If an electrical voltage is applied between these metal plates, then positive and negative charges accumulate separately from one another on their surfaces.

### What is a capacitor?

A capacitor (from Latin condensare 'to condense') is a Passive electrical component with the ability to statically store electrical charge and the associated energy in a direct current circuit in an electrical field.

### How does an isolator work?

A insulator is a component of electrical engineering and power engineering with which bare (i.e. not self-insulated) electrical conductors are attached, held or guided without a significant flow of current through the fastening element.

### What is the capacitance of a capacitor?

The capacity has for different Capacitors different values ​​and depends on the geometry of the conductor and the dielectric. A capacitor so owns the capacity 1F, if with an applied voltage of 1V there is a charge of 1C on the capacitor is located.

### What do you need a capacitor for?

As an energy store to supply a consumer with energy. Example: A battery needs to be changed on a system. In order to bridge the power failure during the change, a previously charged one is charged capacitor discharged during the change.

### What happens if the capacitor is defective?

When the capacitor is broken is, then there are usually the following signs: The engine no longer turns or turns only with difficulty. The engine does not start and hums.

### How can I tell that the capacitor is broken?

The capacitor can overheat and possibly break if overvoltage occurs. The surge of a Capacitor can occur if: the engine speed of the generator is too high. too heavy a load is switched off.

### How is a capacitor connected?

A cable of the Capacitor to the neutral conductor of the supply line - then it turns left, and if you connect it to the phase - then it turns right. The other cable of the capacitor to one of the motor phases.

### What does a capacitor do in the AC circuit?

in the AC circuit lets the capacitor through the stream. Here, too, it acts like a resistance. Due to the constantly changing direction of the current, the capacitor constantly charged and discharged. A current flows through it practically all the time, with no real flow taking place.

### What does a condenser do on a pump?

In all cases, the capacitor to generate the phase shift required for the rotating field in the form of the so-called auxiliary phase. ... The reactive current through the capacitor causes a phase shift on the second winding and forms the auxiliary phase.

### What is an electric dipole?

A electric dipole (from Greek di- "two-") is an arrangement of two point charges of the same size and of different names at a distance d. That produced by them electrical Field is called dipole field.

### What is the dipole moment?

a molecule, an electrical charge of different sign in different places, d. H. if the center of gravity of the negative charges (electrons) and the center of gravity of the positive charges (atomic nuclei) do not coincide, this body has an electrical one Dipole moment. The body is then a dipole.
