Space charge polarization is a type of polarization that arises in dielectric materials due to the accumulation of immobile charges at the interfaces or inside the material. This polarization occurs when an electric field is applied to the material, causing the charges to redistribute and create a net dipole moment in the material. It is one of the mechanisms responsible for the dielectric properties of materials.

Pure water is a poor conductor of electricity. It contains very few ions and therefore has a low electrical conductivity, making it a weak electrolyte.

Collector-emitter saturation voltage refers to the voltage drop across the collector-emitter junction of a transistor when the transistor is in saturation mode. It is the minimum voltage required to keep the transistor in saturation, where the transistor is fully turned on and conducting maximum current.

Ripple marks in sandstone can form due to the heat action of hot fluids or gases moving through the sedimentary layers. This process can cause the sand grains to align in a ripple pattern as the sediment is compacted and cemented into rock over time.

Another egg is triggered to ripen when the brain's hormones signal the ovaries to release more follicle-stimulating hormone (FSH), which stimulates the growth of multiple egg follicles. This typically occurs during the menstrual cycle, with one egg eventually being selected for ovulation.

Water is not a conductor. In fact, some high powered magnetrons are cooled directly by circulating water through the cavity of the magnetron. The water must be ultra pureified to do this though. The slightest of particles will conduct.

Humid air is room air + water vapor, and both may contain contaminates which become more conductive when moisten with higher humidity.

Electrons can carry electrical charge and flow through conductors to create electric current. They also play a critical role in chemical bonding, allowing atoms to form molecules through sharing or transferring electrons. Additionally, electrons are involved in generating electromagnetic fields and radiation.

No, metal is not the only conductor. Other materials like water, graphite, and some types of plastics can also conduct electricity to a certain extent. Conductors allow the flow of electric current due to their free-flowing electrons.

The lawyer ran to the courthouse, was wondering about her case, and eventually decided to eat lunch.

The motor in a gas range works by converting electrical energy into mechanical energy to power the fan or blower that circulates hot air within the oven or helps vent out cooking fumes. When the motor receives power, it spins a fan blade or impeller to create airflow for even cooking and efficient ventilation. Regular maintenance and cleaning of the motor can help ensure its proper functioning and longevity.

Yes, a Sky viewing card will work with a Sky+ box. The viewing card is necessary for accessing Sky subscription channels and services on the Sky+ box. Make sure to insert the card properly into the box for it to work correctly.

To remove a generator from a motor, typically you would: disconnect any electrical connections, unbolt the generator from the mounting points, and carefully lift it out of the motor assembly. Make sure to follow any specific instructions in the manual for your particular generator model.

It depends... If the voltage were applied externally, like to fingers or toes, etc. basically nothing. If the voltage were applied to the tongue, you would feel a tingling sensation, nothing more. If it were applied with electrodes inserted through the chest directly to the heart muscle, it could stop your heart, killing you! It's not the volts that cause damage or pain, its the amps. The higher the voltage, the higher the amps. Also, if the electrodes touch moist tissue such as your tongue, the saline moisture conducts better, causing higher current. If the current gets high enough, tissues start to heat, and enough can cause tissue destruction. 7.5 volts is not high enough to do that, given the resistance of human tissue. But, even low current, if it flows through a muscle, can cause the muscle to contract uncontrollably. This is why even a small current through the heart is trouble. Unless you deliver the current directly to the heart muscle, it takes much higher voltage. If you grab an electrode with each hand, for instance, some current would flow through the heart, but because the skin resistance is so high, it takes several dozens of volts before the heart would be endangered.

Silver is not the best conductor. It is a very good conductor, but not as good as gold. Both metals allow easy movement of electrons. Gold has an advantage in that it will not corrode except under the most extreme conditions.

90 degrees. In an AC circuit with a pure capacitance, the current leads the voltage by 90 degrees. This is because the current in a capacitor is proportional to the rate of change of voltage across it, leading to this phase relationship.

Battery. Analogue (needle type) Voltmeters do not require batteries to display results

I'm pretty sure that if this user wanted a smart remark like yours he wouldn't have posted the question, this website's name is "answers.com" not "smart remarks made by people who have no lives and suck at life.com" thank you. I wish you luck getting the correct answer.

Ditto....this person has nothing else better to do

Watts = Volts x Amps x Power Factor. So as you can see watts and volts are different units and you need to know more information. So if you had 1 microamp of current and 3 million volts you would only have 3 Watts.

You can consider using the silicon transistor 2N3904 as an equivalent for the AC128. The 2N3904 is a general-purpose NPN transistor commonly used in various amplifier and switching applications. Remember to check datasheets and specifications to ensure compatibility with your circuit requirements.

V=IR

To calculate your voltage drop (V), you multiply your resistance (R, measured in Ohms) and current (I, measured in Amps [A]) by each other the. The number you are left with should be your voltage drop.

It isn't. Nothing travels faster than light, especially an electron. If it tried it would become infinitely heavy as it reached the speed of light. You would then need an infinite force to accelerate it further. To know more, Google on "special relativity"

Resonance effect: It is a way of describing delocalized electrons within certain molecules or polyatomic ions where the bonding cannot be expressed by one single Lewis formula.A molecule or ion with such delocalized electrons is represented by several contributing structures called as resonance structures or canonical forms.

Inductive Effect: It is a permanent effect. When group attached to carbon atom attract electrons from them or push the electrons toward it is called as Inductive effect.

False. The total current in a parallel sub-circuit where all resistors have the same value cannot be found by multiplying the current by the number of resistors. In a parallel circuit, the total current depends on the individual resistor values and how they affect the overall resistance of the circuit.

As the cathode rays carry a charge of negative electricity, are deflected by an electrostatic force as if they were negatively electrified, and are acted on by a magnetic force in just the way in which this force would act on a negatively electrified body moving along the path of these rays, I can see no escape from the conclusion that they are charges of negative electricity carried by particles of matter.
