RMS stands for root mean squared, and is an easier way to refer to AC voltage. To calculate Vrms, you just take your peak voltage and divide by the square root of 2. Thus, we get the equation Vp/(2^1/2). For power and amperage the calculation is a bit more complicated, but it's very easy for voltage. Therefore your answers, assuming that your given voltages are the peak voltages of the sinusoid, will be 311.12v, 155.56v and 77.78v respectively. If you want to go from the RMS value to the peak value, simply multiply by the square root of two.

To calculate the RMS (Root Mean Square) of a set of values, you first square each value, calculate the mean of the squared values, and then take the square root of that mean. For the given values (440V, 220V, 110V), you would first square each value (440^2, 220^2, 110^2), then find the mean of these squared values [(440^2 + 220^2 + 110^2) / 3], and finally take the square root of that mean.

Does Korea use 110 or 220 electricity?
South Korea uses 220 volts electricity, whereas North Korea uses 110 volts.
How do you plug in a pot that is 220 to a 110?
Use a step-up transformer from 110 volts to 220 volts. Try getting one at Home Depot or SEARS.
How do you convert a 110 volts into 220 volts in a digital alarm clock with a plug in option?
You would need to use a voltage converter or transformer that can take in 110 volts and output 220 volts. Make sure the converter is rated to handle the power requirements of the digital alarm clock. Additionally, check the compatibility of the plug to ensure it fits the socket of the digital alarm clock.
What is The Voltage Of Mexico?
Mexico has 110 to 120 volts. SOME AREAS 220.
Fuse to protect 110 volt from 220 volt?
Using a fuse will not protect a 110-volt appliance from 220 volts. You will need a voltage converter or transformer to step down the voltage from 220 volts to 110 volts to protect the appliance. It is important to use the correct equipment to ensure the safety and proper functioning of the appliance.
Does Korea use 110 or 220 electricity?
South Korea uses 220 volts electricity, whereas North Korea uses 110 volts.
Can you plug iPod Nano to a 220 volts to charge?
110 volts
How do you plug in a pot that is 220 to a 110?
Use a step-up transformer from 110 volts to 220 volts. Try getting one at Home Depot or SEARS.
How will a 3 phase panel give you 110 volts and 220 volts?
A three phase panel will not give you 110 and 220 volts. A three phase four wire panel will, but not at these voltages. The nearest voltages will be 120 and 208 volts. The 120 volt is the wye voltage of 208 volts. 208/1.73 = 120 volts. A single phase three wire panel will give you 110 and 220 volts.
What are examples of voltage?
220 volts, 110 volts, 440 volts, 400 volts, AC or DC voltage. High voltage like - 220 KV, 400 KV, etc
Does China use 220 or 110?
China uses 220 Volts AC for household electricity
How do you connect 2 110 volts brown wires two blue wires and two ground wires in a 220 volts fuse box to converts 110 into 220 volts?
The specific colours of brown and blue suggests that this is a question from the UK or European area. On checking the IP address it shows that the question comes from Uruguay. 110 volts is not a common voltage to this area, so that 110 volts can not be converted to 220 volts because 220 volts is the common working voltage. If the question is asking about using 120 volt equipment in that country see related links below.
Can 110 volt apliance work on 220 volts circuit?
NO - that is dangerous.

i have no idea
What is the difference between 3 phase 440volts distribution and 3 phase 220v distribution?
About 220 volts. They're just different voltage levels. 440 volt services can provide more power than 220 volt services typically.
