That is a wrong question, because the house has to take the voltage, the power station is delivering.

Either 120 volts in the USA or 230 volts in Europe.

Volts are never consumed.

Most residential power is supplied as 240 volt. A more important factor would be how many amps the service is sized for. Most modern residential services are supplied 200 amp service, which should be sufficient for an all electric house.

In the UK the service rating is 60 amps at 240 volts.

In North America the average is 100 to 150 amps. All new homes being built today usually have a 200 amp 42 circuit distribution panel installed.

Why transformer is rating kva?

the short answer: to distinguish as an AC transformer, as opposed to a DC transformer. The long answer: A Kva stands for Kilo-Volt-Amps. The transformers mounted on telephone poles work with hundreds of thousands of volts so rather than 750,000 V, we use the abbreviation kilo, being the metric prefix for thousand and write 750 kV. As for 'VA' some high school physics tells us Voltage*Current=Power. voltage being measured in volts (V), current in amperes or amps for short (A), and power being Watts (W). However alternating current is a very fickle beast and the voltage and current vary in a wave like fashion causing the power to reverse direction. Other factors come into play such as power sag, types of electrical loads, and wasted energy, the equation soon becomes very messy. at times the power is actually negative and is flowing away from your house! so to simplify things they use Volt-Amps to represent the maximum amount of power as an absolute value that the electricity can deliver. as opposed to the USEFUL amount of power which is lower due to resistances in the wires and other loses. Engineers have to worry about the KVA when designing a system so it can handle everything thrown at it, keeping the wires from melting and that transformer from blowing up!


Techniques required for increasing the input impedance?

...of what? to a house, to a breaker (to lower fault current level?), to an amplifier circuit?


Why alternating current is represented by sinusoidal wave form?

AC voltage, like the voltage in your house, is typically referred to as 120vAC. This means the voltage swings 120V positive and 120V negative 60 times per second (60 Hz) 360 degrees total (sine wave). Current and voltage go hand-n-hand so the current alternates with the voltage. the RMS value is what we experience at the output (160vAC is actually sent to the circuits)


Why is the electric current you receive at your house is called alternating current?

The voltage and current are delivered in a sine wave that goes positive and then negative at 60 cycles per second. Google sine wave to see what a sine wave looks like.


What are advantages power supply in computer?

The power supply converts the high voltage (e.g. 120VAC in US, 240VAC in Europe) alternating current house electricity supply down to the various different low voltage direct current supplies needed by different devices that make up the computer. These low voltage direct current supplies are tightly regulated in the power supply circuitry to prevent transients in the house electric supply from perturbing the computer's electronics as well as to compensate for variations in power demand as the different devices that make up the computer operate.

Will a fan requiring 230 volts ac run on normal house current?

Yes if the house supply is 220-240 volts. The required voltage range should be printed somewhere on the fan.


What is the difference between ac voltage and dc voltage?

access current ( like plugs in your house ) direct current (like batteries)


Are high voltage transmission lines 60Hz like the wiring in a house?

Yes, the frequency stays the same. Only the voltage and current change as the voltage is stepped down.


What is the same in a parallel circuit?

Always voltage constant in parallel circuit if you look your house wiring all are in parallel therefore 220 volt present in every house but current is different


How does ac dc power supplies work?

The mains to the house is an alternating current and this high voltage is stepped down using a transformer. The low voltage secondary alternating current is converted to direct current using 4 diodes wired as a bridge rectifier. The 'lumpy' direct current is smoothed using an electrolytic capacitor to smooth the resulting dc. It may need to be voltage regulated if the circuits it feeds are voltage sensitive.


How much electricity does a house need?

its not a question of voltage but current(amps) a load calculation needs to be done to determine service size required refer to section 8 of the cec CIRCUIT LOADING AND DEMAND FACTORS section 8-200 (1)


What is the voltage that causes the most human deaths each year?

120 volts A/C, or some might refer to it as house current.


How do you check a transformer for ac house unit?

Check that the input and output voltages are as required. Check that the transformer is big enough for the current required for the unit you have.

Can you run 125v air conditioner on 120v house current?

Yes ,it's the same voltage.You have a +-5% of voltage range


How do you power a whole house with one generator?

Use a generator with a high enough rating to power the house, of course. Trying to power a house that draws 60A of current with a 10A generator is just never going to work.
