If you reside in North America your power supply is 120/240 single phase. These are nominal voltages and can be varied by plus 6% or minus 8%. Regular appliances and lighting use 120 volts. Larger appliances use 240 volts. This includes electrical heating , hot water tank, range top, oven, electrical dryer and larger size motor loads.

Why is it possible to measure an electric potential across the terminals of a dry cell?
Batteries are a voltage storage device that hold a voltage potential until used. By using a volt meter you can find the stored voltage by placing the leads of the meter across the battery's positive and negative terminals.
How many amps are in a 360 watt vacuum?
To calculate the amperage, you would need to know the voltage that the vacuum operates at. As a general formula, Amps = Watts / Volts. Assuming a typical household voltage of 120V, using this formula you would have around 3 Amps for a 360 Watt vacuum cleaner. However, actual amperage may vary depending on the specific voltage of the vacuum.
How many amps does your electric recliner chair use?
The amperage used by an electric recliner chair typically ranges from 1 to 3 amps, depending on the model and features. Most electric recliners operate on standard household voltage (120V in the U.S.), so you can estimate the wattage by multiplying the amps by the voltage. For example, a chair using 2 amps would consume about 240 watts. Always check the manufacturer's specifications for precise electrical requirements.
How many amps can a 2.2 megohm resistor handle?
A 2.2 megohm resistor can handle very low current because of its high resistance value. Using Ohm's Law (I = V/R), at a typical voltage of 5V, the current would be around 2.3 microamps.
How many amperes use an electric heater?
The amperage of an electric heater depends on its power rating in watts and the voltage it operates on. To determine the amperage, divide the wattage by the voltage (Amperes = Watts / Volts). For example, a 1500 watt electric heater running on 120 volts would use 12.5 amperes (1500 watts / 120 volts = 12.5 A).
What methods are commonly used for electric field measurement?
Common methods for electric field measurement include using a voltmeter to measure voltage, using a field mill to measure electric field strength, and using a Faraday cage to shield from external electric fields.
Explain the rheostat and its advantages in electric circuits?
Advantages in electric circuits : Advantages of using the rheostat in electric circuits is optional as you could just use the dial on the power-supply to vary the voltage (p.d.), and therefore the current. The advantage of using the rheostat is that you can control it to give you nice even numbers for the voltage.
What will be the maximum electric field in this filament?
The maximum electric field in the filament will depend on factors such as the voltage applied and the material properties of the filament. It can be calculated using the formula E V/d, where E is the electric field, V is the voltage, and d is the distance across the filament.
How can the flow of electric current be altered or modified?
The flow of electric current can be altered or modified by changing the voltage, resistance, or by using devices like switches, resistors, capacitors, and transistors in an electric circuit.
Why is series connection not used for domestic purpose?
220 - 240V is the general limit for the house hold purpose and the same voltage should be supplied for all the electric componets which are using. We know, voltage will get drop after passing resistor/electric devices (which are consuming the voltage). If all components are in series, then voltage will be very less for the electric componet which is placed at last in series connection. For this reason, all connections should be placed in parallel, so that voltage will be same for all electric devices. I hope what i sad is correct. Raju (Mechanical)
What is the voltage at the location of a 0.0001-Coulomb charge that has an electric potential energy of 0.5 joules?
Electric Potential = Electrical Potential Energy/ Charge The measurement for electric potential is call the volt. Electrical Potential is often called voltage. Voltage or Electrical Potential = 0.5 Joules / .0001 Coloumb = 5000
What are the benefits for using low voltage lighting in the home?
Low voltage lightning is not only pleasing to the eye, but it also saves you a ton of money on your electric bill. Low voltage lighting is often better than high voltage lighting in rooms that you use infrequently.
What is the purpose of using transformer in electric bell circuit?
To supply the bell, because the latter has a rated voltage that's lower than the mains.
A proton is in an electric field and has an electric potential energy of 0.5 J What is the electric potential voltage that it experiences?
First off you know that when it says "Proton" you should know that its a Positive (+) Charged subatomic particle! Now You use the equation that says --> Volt = Electric Potential Energy / Q Volt = 0.5 / +1 (proton) Volt = 0.5
If the resistance of an electric current is 12 ohms and the voltage in the current is 60 V the current flowing through the circuit is?
..using the formula Voltage(V)=Current(I) * Resistance(R) .. we can get the result ...current will be 5 Ampere
What do electric substations do?
Electric substations either step up voltage or step down voltage for electric power distribution. For example, power being generated at a power plant would be stepped up in voltage for transmission over the electric grid. On the other hand, power coming into a residential neighborhood from the electric grid would be stepped down in voltage for distribution to individual homes. This increasing or decreasing of voltage will be accomplished by using transformers in the substation. There will also be electric circuit breakers in the substation located on both the high and low voltage sides of the transformer. These circuit breakers are used to be able to isolate the transformer from the electric grid for maintenance purposes or in case of an electrical fault that could damage the transformer. Most substations will also contain a Control House that contains all of the control equipment for the substation as well as battery backups in case of loss of power. Type your answer here...
How you would use the water flow to demonstrate a low-voltage electric current?
In a water system, the "voltage" is the water pressure, the flow rate is the "current", and the pipe size is the "resistance". Low-voltage electrical current is equivalent to low-pressure water.
