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 else can I help you with?
Is a house direct or alternating current?
The current flowing in a normal household lighting electric bulb is AC. DC systems are just a fraction of 1% in ordinary household systems.The current flowing in a flashlight bulb is Direct Current (DC) if the flashlight runs on batteries.
Is noise is a alternate current or direct current in a circuit?
Noise in a circuit typically consists of alternating current (AC) components, but it can also include direct current (DC) components depending on the source of the noise. AC noise may come from electromagnetic interference, while DC noise could be caused by sources like power supply issues.
On which current does fan rotate?
Most fans operate on an alternating current (AC) as it is the standard electrical power supply in homes and buildings. However, some fans, like those in vehicles or powered by batteries, may operate on direct current (DC).
When charges shift from flowing one direction to another what current is there?
From your question it sounds like alternating current.
What is alternating current normally produced by?
Alternating current is typically produced by generators, which convert mechanical energy into electrical energy by electromagnetic induction. These generators are commonly found in power plants, where various energy sources such as coal, natural gas, or renewable sources like wind or hydro power are used to turn the turbines.
What does the letters acdc stand for in the rock band?
AC is alternating current like in your house. DC is direct current like in your car.
What is the differences between direct circuit and alternating circuit?
Direct current and Alternating both are diffrent . Alternating current changes it's cycle 50 times in both direction in one second while the direct current doesn't change it's phase or frequecncy because it is free from frequency or frequency less(direct current).
What is an example of a direct current?
A direct current (DC) is the continuous flow of electric current that circulates in one direction and keep the same polarity (positive or negative). Example of direct current are batteries and generators. There are electronic devices, like computers, that work with direct current, but they require of some additions to convert alternating current to direct current.
Current that reverses direction in the regular pattern is called?
This is known as a direct current or DC. The two major types of currents are AC (alternating current) and DC (direct current). In AC the charges move back and forth, but in DC the charges flow in JUST ONE DIRECTION. Due to this characteristic it will not reverse direction like AC can.
Which type of current does lightning has?
unfortunatley i cant tell for sure what you mean because of the lack of grammer (not insalting you) but if your asking wether it has direct current (DC) or alternating current (AC) like i think you are than the answer is direct current (DC)
Electric current changes direction repeatedly is called?
AC current (alternating current) like in a wall outlet
Is a house direct or alternating current?
The current flowing in a normal household lighting electric bulb is AC. DC systems are just a fraction of 1% in ordinary household systems.The current flowing in a flashlight bulb is Direct Current (DC) if the flashlight runs on batteries.
What does AC DC stand for in science?
AC or Alternating current, DC or Direct Current. DC is relative to most battery voltage systems, cars, pocket radios, so on. Alternating Current mainly relates to your household electric. Each differs in the way the electric is passed through the system, or battery. Unless your talking about the Rock Group, then I do not know there meaning or definition. Groups have there own language for things like that. It does not stand for After Christ / Devil Comes.
What is the function of inverter?
An inverter is an electronic device that converts direct current (DC) to alternating current (AC). It is commonly used in power systems to operate AC-powered devices, such as household appliances, from DC power sources like batteries or solar panels. Inverters are essential for providing electricity in off-grid or remote locations.
What is different between alternating current and direct current?
Direct current is constant - always in the same direction. Alternating current regularly changes direction; for example, in household current, 50 or 60 times (that is, full cycles) in every second.See the Related Link below for more information about the difference between alternating current and direct current.
What does the Induction motor do that Nikola Tesla invented?
The induction motor is an alternating current motor that Nikola Tesla invented. It generates motion by inducing a current in a rotor when coupled with an alternating current power source. This design allows for a simpler and more efficient electrical motor compared to direct current motors.
What is a DC charge?
DC = direct current, it is a steady charge that keeps going the same direction. AC = Alternating current, it is a charge that changes direction very quickly. The positive and negative keep switching.
