What type of current only consists of direct current at a low voltage and high amperage?
battery
What happen to the current when the voltage increased if the resistance are constant?
If voltage increases when current remains constant then resistance must also increase. Ohm's Law: Voltage = Current times Resistance.
What determines whether an induced current is a direct current or an alternating current?
There is no such thing as an 'induced current'. What is 'induced' is a voltage. The direction of the induced voltage is determined by the direction of the changing current that induces that voltage, because the induced voltage will always act to oppose that change in current. So, if the current is increasing, then the direction of the induced voltage will act to opposethe increase in current. If the current is decreasing, then the direction of the induced voltage will act to sustainthat current.
What is the relationship between voltage power and current?
The unit of power is watts, the unit of current is amps, and the unit of voltage it volts. Power = Voltage X Current Voltage = Power / Current Current = Power / Voltage In electricity, power is symbolized with a P, current with an I, and voltage with a V. The real formula looks like: P = V x I V = P / I I = P / V
What factors determine the voltage induced in a wire?
V = I * R or I = ( V / R ) I = current (amps) V = Voltage R = Resistance The current in a circuit depends on the applied voltage and the resistance of the circuit.
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.
In electric terms what do the abbreviations AC and DC mean?
Its Alternate Current and Direct Current. I believe Angus Young got the idea for the band name when he say AC/DC on the bottom of his sisters sewing kit. Electric current can be direct current (DC) or alternating current (AC). Direct current such as the power from dry cells is characterized by a uniform direction of flow and amount (voltage) of electricity.
What are the kinds of voltage?
Alternating current - AC, and direct current - DC.
When voltage is reduced 75 percent current is reduced?
This statement is correct.
What is DC in voltage means?
This means direct current.
Merits and demerits of direct current distribution?
In direct current the voltage and current remain the same at all times. Direct current is more efficient when traveling longer distances, but has a higher loss rate when distributing to many people and its much harder to change the voltage.
How are batteries a source of direct current?
Batteries are a source of direct current because they product power (voltage and current) in only one direction.
What is the meaning of DC Voltage?
D.C. stands for direct current. A.C. is alternating current.
What is the difference between ac voltage and dc voltage?
access current ( like plugs in your house ) direct current (like batteries)
What is the Difference Between VAC and DC Current?
VAC is voltage of alternating current signalDC current is amperage of a direct current signalAnswerYour question contradicts itself, as the symbol, V,represents voltage, not current.However, V a.c., represents an alternating voltage -one in which the direction in which the voltage is acting continuously reverses itself. Vd.c. represents a direct voltage, in which the voltage continuously acts in the same direction.
What type of current only consists of direct current at a low voltage and high amperage?
battery
Is vac and watt the same?
No, VAC is in direct reference to Voltage Alternating Current. This is much different than VDC which is in direct reference to Voltage Direct Current. The term volts refers to all voltages and does not specify what type it is.
