In what two ways is it possible to generate a higher voltage in a moving conductor?
Bernadethrodriguez02...
The two ways of generating a higher voltage in a moving conductor are: 1. Increasing the speed of relative motion between the coil and the magnet 2. Increasing the strength of magnetic field.

Why is it important that the rotor is as high up in the sky as possible on a wind turbine?
The higher you go, the stronger the wind. Strong wind will generate the most electricity.
What is the cause of conduction?
Heat conduction (heat flow) is caused by a temperature differential along the heat conductor. Heat flows from higher to lower temperatures. The heat flow is proportional to the temperature difference times the thermal conductivity. Electrical conduction (electric flow) is caused by a voltage differential along the electrical conductor. Electricity flows from higher to lower voltages. The flow is proportional to the voltage difference times the electrical conductivity. Water conduction (water flow) is caused by a pressure differential along the water conductor. Water flows from higher to lower pressures. The flow is proportional to the pressure difference times the water conductivity.
Why do electrons flow through a wire?
An electrical current is simply the flow of free electrons in and on the conductors. So they are a bit like water molecules in a garden hose. And like those water molecules the flow of free electrons can be physically impeded by whatever is in or on the electrical conductor. When a material is a good conductor, the atoms and molecules of that good conductor do not get in the way of the free electrons. They do not resist the flow of those electrons very much. So even with just a low voltage to push the electrons along, the flow, the current of the electrons is high. But when a material is a bod conductor, the atoms and molecules of that bad conductor do physically get in the way of those free electrons so that they cannot flow freely through the conductor. The resistance is high in a poor conductor. So it takes a relatively higher voltage to push electrons along in a bad conductor...if indeed they can be pushed at all. Some materials are so bad at conducting it's almost impossible to move those electrons along.
How does voltage gradient affect separation of charged particles in an electric field?
There is a direct relationship between the voltage gradient of an electric field and the separation of the charges. Higher voltage gradients will separate charges farther.
What is the amount of current flow through a wire?
The amount of current flowing through a conductor is governed by the amperage of the connected load. This is why there are different sizes of conductors. Each conductor size is only allowed a specific amount of amperage to flow through it. If the amperage load is higher that what the conductor is rated for then the next larger size conductor has to be used. The limiting of the amperage to specific size conductors keeps the conductor from heating beyond the conductors specifications, under full amperage conditions.
The larger the conductor the Higher the resistanc Lower the ampacity Higher the voltage Lower the resistance?
No. The larger the conductor the lower the resistance and the higher the ampacity.
Can Two or more batteries connected in series generate a higher voltage than one alone?
Yes, two or more batteries connected in series can generate a higher voltage than one alone.
Can rheobase be a threshold stimulus?
Yes, it can be because threshold and rheobase both are the voltage required to generate an action potential. The difference lies in that the treshold can be a voltage higher than rheobase.
When testing a power transformer with an ohmmeter which winding should have the largest ohmic value?
The higher-voltage winding has more turns (therefore its conductor will be longer) than the lower-voltage winding and, because it will carry less current, its conductors will have a lower cross-sectional area. Consequently, the higher-voltage winding will have a higher resistance than the lower-voltage winding.
Do conductors have low resistance?
Conductors have low resistance. Recall Ohm's law. The higher the conductor resistance, the greater the voltage drop along the conductor, and the less voltage that is available for the load. The conductor resistance is a resistance in series with the load. Also, higher conductor resistance results in more electrical power being converted into heat, warming up the conductors. This is calculated with the formula P=I2R. The greater the resistance, the greater the power wasted heating the conductors.
Why should someone generate power at 220 V?
Only small personal generators generate a voltage of 220 volts. This level of voltage is used usually during power outages. For voltages that power the electrical grid, the voltage is generated at a much higher voltage and then transformed by the use of transformers, into the voltage that is required by different distribution services.
Is gold used in circuit breakers?
Certainly not in the case of high-voltage circuit breakers. Probably not in low-voltage circuit breakers, as copper is a better conductor and has a higher melting point.
Conclusion of voltmeter?
The higher the resistance , the higher the voltage
What is a output voltage?
You can compare a power supply to a waterfall of energy. The high of the waterfall is the output voltage, and the quantity of water in the river is the current intensity. The power generate is a combination of the intensity and the voltage: P=UI (the effective power is the result of the multiplication of the voltage and the intensity). That explain why higher the voltage is, less intensity is needed to have the same power. It is the same in a waterfall, higher it is, less water you need to make a mill turning.
Electrons flow from areas of higher to lower voltage or from areas of lower to higher voltage?
Electronsflow from areas of lower to higher voltage, while Current flow from areas higher to lower voltage.
What is good in aluminum?
Aluminum is a metal. It can be used as * reducing agent in the metal extraction. * Good conductor of heat and electricity. * Cheap when compared to Copper. * used in transportation of the power of higher voltage.
How is 4160 voltage made?
Well first we need to generate voltage from electrical generator. Then if voltage are below 4160 volt step up Transformer is used and if voltage are above 4160 volt step down Transformer is used. Generally voltage produced from generator are low so we need to step up voltage to higher values such as 240 kilo volt to transmit them to longer distances to reduce power losses.
