More electrons means more current, by definition.

Describe the relationship of the parts of an electrical current?
I assume you mean Voltage, Current and Resistance. Voltage (E)or electromagnetic force is the electrical pressure or force that forces the electrons through any given circuit Current (I)is the flow of those electrons through any given circuit Resistance (R) is anything within the circuit that would restrict the flow of electrons
What does 10 volts mean?
Volt is the unit of voltage. It refers to the difference in energy per unit charge, when you move electrical charges between two points.Another good way to think about voltage is to think about Ohm's Law: V=IR. Through a given resistance, a higher voltage will produce a larger electrical current (more electrons per second).
Is velocity of electrons increase by increasing voltage?
Depends on what is between the potential difference (ie, the voltage). If it's an evaculated tube, and the electrons are travelling between the anode and the cathode without much interference, then then a higher voltage will mean that the electrons arrive with more kinetic energy -- ie, increased velocity. However, if there's a wire between the two voltages, then the drift velocity of the electrons (which is pretty slow to begin with) does not increase, but only the number of electrons that are drifting.
How many electrons are there in higher energy Carbon?
It depends on what you mean by 'higher energy'.
What is term used when an Alternating current acts like a direct current?
Perhaps you are asking how the voltage of alternating current is measured, to be equivalent to the voltage of a direct current system. Alternating current and direct current have distinct properties. With direct current, voltage is at a constant polarity, and a direct current voltage source will maintain a uniform, constant voltage level. Alternating current reverses polarity at a given frequency and therefore it's voltage continuously varies from a positive peak voltage level, through zero, to a negative peak voltage level, repeating this cycle continuously. For this reason, voltage of an alternating current system, is measured in root-mean-square (rms), which is a voltage, which when multiplied by the current in amperes, calculates power which is equivalent to that of direct current of the same voltage and current values. With a typical sinusoidal waveform, the peak voltage of alternating current is divided by the square root of 2 to determine the rms voltage. The 120 volts output in the wall outlet in our home is actually about 170 peak volts.
What do you mean by Polarity for the following Electrical parameters Charge Voltage Current Meter probes?
Charge, + charge is a lack of electrons, - is an excess of electrons, compared to a reference point. Voltage, + voltage is measured at a point that has a lack of electrons, compared to a reference point. Current, + current flowing through a wire indicates that electrons are flowing in the opposite direction Meter probes, see voltage above.
What does voltage and ampere mean in very simple terms?
Voltage is how fast electrons move. Current (Amperage) is how many electrons are moving.Think of a water hose shooting a small jet of water; the water is moving very fast (High voltage, low current)Now think of a wide river flowing slowly, not a lot of motion but a very lot of water (Low voltage high current)

Does a high rating mean lots of insulation or little insulation?
It depends what you mean by a 'high rating'!If you mean a high 'voltage rating' then, yes, you will require thicker insulation. But if you mean a high 'power rating', then, not necessarily, because the voltage can be low, while the current is high.Remember, the thickness of insulation depends on the voltage, while the type of insulation (how it withstands higher temperatures) depends on the current.

What mean by va in current transformer?
Its simply multiplication of voltage applied and current.
What do a direct electrical current is different from an alternating current because only the direct electrical current means?
In Direct Current, electrons flow from the negative pole of the electrical source, through the load, to the positive pole of the electrical source. Current is constant as there are no variations in voltage over time in the circuit. Voltage and current are measured by directly measuring the voltage and current in the circuit. In Alternating Current, electrons also flow from the negative pole of the electrical source, through the load, to the positive pole of the electrical source. However, the polarity of the poles changes +/- to -/+ to +/- , alternating polarity over and over again. This causes the direction of the electrons in the circuit to change each time the source poles change polarity. Current and voltage are not constant in an AC circuit as they vary with the waveform generated by the electrical source. In many, but not all cases, voltage and current are measured by the RMS (root-mean-square) method as directly reading the peaks of the AC waveform will not indicate the correct amount of energy in the circuit.
What does the electronic term Vb mean?
Base voltage in a transistor. There is also Vc (Collector voltage), Ve(Emitter voltage), Ic(Collector current), Ib(Base current), Ie(Emitter current), Vcc(Supply voltage), and Hfe (Forward current gain)
What does current mean in physics terminology?
current is flow of electrons through conductor
When ac convert in dc then voltage will increase or decrease?
You can make it so it does either increase or decrease. The limiting factor is that power out cannot exceed power in. So going to a higher voltage will limit current and going to a lower voltage will increase current available. A2 Because AC is continuously changing in a sinusoidal waveform, it is hard to determine the exact voltage. It is usually called by it's RMS value (Root Mean Squared). The result is that when you fully rectify an AC voltage, the DC voltage is actually HIGHER than the RMS AC voltage.
What does voltage current mean?
V=IR, voltage is directly propostional to current and resistance (by ohm's law).CommentVoltage is not 'proportional to resistance'. Resistance is a constant, and is not affected by voltage at all.
