Typically in the US, voltage is +/- 110-120 volts AC RMS (so you can get 240 total), and a typical service will be 100 Amps (I believe, but I could be wrong on "typical" here). This doesn't mean the home uses 100Amps, it means this is the peak amount the home is allowed to draw.

Another (more accurate) perspective.Current is measured in Amps, not volts as the above answer suggests, and it would be necessary to determine the expected load that YOU plan on using in your home before anyone could make an accurate estimation for you.However, 200 Amps is not a bad place to start. Plan on a meter base and breaker panel rated at 200 Amps, and go up from there if you think there is likely to be more need. The size of the home, whether it is to use heat pump for all of the HVAC needs, any other special requirements... all factor in to the size of service you should put into a new home.
Remember that it's always easier to install more capacity than you need, then just use less than that. If you install a main service that is underrated for your needs, you will constantly have problems.
Contact a qualified electrician in your area to help you calculate the electrical current needs of your home. The local electrician should be familiar with local building codes and practices.

What is Magnitude of the voltage or current?
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).
If a toy car with a resistance of 2 ohms is connected to a 3v battery how much current flows through the car?
Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).Ohm's Law: V = IR (voltage = current times resistance).
An electric heating element has a resistance of 16ohm and is connected to a voltage of 120v How much current will flow in the circuit?
Ohms law states that E=I * R, or voltage equals current times resistance. Therefore current equals voltage divided by resistance. 120v divided by 16 ohms equals 7.5 amps.
How much current flows through a resistance of 300 ohms if the power source is 15 volts?
Ohm's Law Voltage = Current x Resistance Answer is 15/300
What is the importance of determining of resistor values?
it is used to check or verify how much current pass through the circuit using voltage source.
How much current does a 23 watt bulb consume?
To answer this question a voltage must be given.
What is the meaning of 'voltage drives current'?
Think of Voltage as the pressure and Amperage (current) as flow. If you think of it as pipes with water then the pressure would be voltage, and current would be how much water flows past a certain point in the pipe in a given time.
What is Magnitude of the voltage or current?
"Magnitude" means how strong it is - how much voltage (how many volts), or how much current (how many amperes).
How much load current of an ac?
Load current is simply the name given to the current drawn by a load from its supply. In the case of a d.c. circuit, this is determined by dividing the supply voltage by the resistance of the load; in the case of an a.c. circuit, it is determined by dividing the supply voltage by the impedance of the load.
Given a circuit has voltage supply of 12Volts and load resistance of 20ohms how much current is expected?
v=ir 12=i20 i = 0.6 Amp
Why does the voltage need to be so high in a power station?
In long range,electric current can flow only when the wires are given high voltage.The voltage is about 20-30kV.eg.lightning. ---------------------------------------- Current of any voltage can flow in a wire. However, the larger the current is, the larger the resistance to flow and the greater the loss of energy during transmission. Therefore, to transfer the same amount of energy per second (power) without as much loss of energy due to resistance, current needs to be lowered by increasing the voltage since Power = Current * Voltage.
How much current flow in 1 watt bulb?
Everything Depends on the voltage supply ...... Current flow (Amp) = Watt / Voltage the Current flow will be 1 amp if voltage is 1 V the Current flow will be 0.5 amp if voltage is 2 V the Current flow will be 0.25 amp if voltage is 4 V and so on.......
How much current would a 15W light bulb draw if it had 120 volts applied to it?
Basically, Power = Current*Voltage Current = Power/Voltage Current = 15/120 Current = 0.125A or 125mA
How much current was in the circuit?
I'm sure I can answer this if given more details, what circuit? current is determined by voltage and impedence(resistance) in a purely resistive circuit it is pretty basic, in alternating voltage circuits the impedence is dependent on the frequency of the voltage/current. inductors and capacitors are designed into a/c circuits to force the load to behave like a resistive circuit which boils down to how much voltage divided by how much resistance you have, 120 volts divided by 10 ohms equals 12 amps. in a parallel circuit it works pretty much the same way voltage placed on the resistor divided by its resistance equals the current flowing through that leg. more details please.
How much transient current for 930 kw motor?
The current depends on the supply voltage.
What is Difference Between Current Source and Voltage Source?
A current source varies the output voltage to maintain the desired current. A voltage source has a constant output regardless of the current draw (up to the capacity of the supply, of course).
How do you figure out how much current is in an electrical wire?
If you know the voltage and resistance, then current = voltage divided by resistance. Otherwise, you can attach an ammeter into the circuit (in series).
