If you measure the current coming from a wall outlet in your house will it give the same reading the meter uses to compute your home energy use?
Canada and the United States (along with most of the rest of North America and some of South America) use a connector standardized by the National Electrical Manufacturers… Association. The outlets feature two slotted inputs for the electrical current and one hole for the ground.

How much power in watts does an electric clothes dryer use if it draws 20 amps of current from a 240 volt wall outlet?
4800 watts because watts = volts x amps.
Alternating Current (AC), which means it changes from positive to negative at a frequency of 50 or 60 cycles per second. In USA, Canada and other countries which use simi…lar standards for mains electricity supply, the voltage coming into the house is usually an average of 240 Volts AC. This is split into two, with a common neutral wire, so that 120 Volts AC is the voltage supplied from most ordinary socket outlets. Some high powered appliances, such as kitchen stoves or ranges, water heaters and dryers, run at the full 240 Volts. In Europe and many other countries the alternating current changes from positive to negative at a frequency of 50 cycles per second. The voltage coming into the house is usually an average of 230 Volts AC and that is what is supplied from most ordinary socket outlets. As in the US system, high powered appliances, such as kitchen stoves or ranges, water heaters and dryers, also run at 230 Volts.
In US, 110V - 60Hz AC power is supplied for domestic household use. -Abhiraj Chauhan (firstname.lastname@example.org)
In batteries Direct current is used (DC). This is because Batteries do not last very long and therefore are made to have certain voltage that can be used in most electronics. …Batteries can be very hazardous if there is a short circuit that occurs. In households the outlets are a form of Alternating current (AC). This is because AC is easier to use and has no big hazards (unless you stick a fork in the socket). If some of the outlets give out (die or burn out) the rest of the remaining sockets in that same area will still work.
Using DC the problem can be electrolytic action in the material being tested that causes the reading to change with time. AC prevents that happening.
It depends how big your house is! Meters is normally best for us with modest size houses.
If you had a multimeter and plugged it into a 120V wall outlet what electrical current would it read?
If the meter was set for "current" (amps) and the leads were connected to the current input, you hope it will read 0. -- It should blow the fuse inside. If the meter is set …for volts AC, it should read anywhere between 108 and 132 volts. If the meter is set for volts DC, it should read close to zero. If the meter is set for resistance (ohms) it would probably display an unstable reading, or could damage the meter. And finally, is this a trick question, and you are really talking about a 120V AC powered benchtop multimeter? In that case it would read whatever current is flowing in the circuit under test, provided the meter is set up correctly. A multimeter can test: ac current with a clamp on meter around one wire or ac or dc current in series with the load. A multimeter cannot test dc current with a clamp on meter (there is no frequency in dc to create a field) Another answer I would think someone asking a specific question about a multimeter would assume that person knows what they're doing, and would connect it correctly. When I connect my multimeter to the 120V wall outlet I get 126 volts - the display is stable to within about a half a volt. I have a Keithley multimeter, as well as a Simpson analogue VOM. I just measured line voltage again, this time getting 123 volts. This is reasonable, as there is no load on the line. With the toaster on, it drops to 118 volts. This is probably within whatever tolerance is built into the system. Comment: Because the standard tolerance for 120 volt services is " + or - 10%", those voltages you measured are certainly ok: those readings fall between the minimum tolerance limit of 108 volts and the maximum limit of 132 volts. The actual voltage you are using at any instant in time doesn't only depend only on the load you have applied to the branch circuit, it also depends very much on: the length of cable-run from the step-down distribution transformer nearest to your home (located in an area substation or up overhead on a pole in the street) and how many of your neighbors are putting on their electric toasters and/or kettles at the same time as you are! Voltage or current? I notice the question mentioned both voltage and current. I don't know whether this was a typo. It would seem strange to ask how many volts you get from a 120V socket. The voltage version of the question has been answered quite comprehensively, so I'm going to answer the current version. Voltage and current are different things, not just the same thing measured in different units. It doesn't make sense to ask "how many volts in an amp?" (which is essentially the question that's been asked). Electricity is analogous to water flowing through a pipe. Voltage is like the pressure difference between the two ends of a pipe; current is like the flow rate (in liters per second). In an ideal world, an ammeter (current measuring device) has resistance 0, while a voltmeter has infinite resistance. Obviously, these are only ideals which can't quite be reached in practice. So the question is: Just how low is the resistance in your ammeter? Use the equation V=IR to calculate the current. I.e. the current is 120 volts divided by the resistance.

N electric clothes dryer draws 22 A of current from a 240V wall outlet How much power in watts does it use?
The formula you are looking for is W = I x E. (W is watts, I is current in amps, E is volts) <<>> 5280 N
The main one is that you don't have to bare the wire to take the measurement so your chances are getting a shock are practically nothing.
Can you use an oscilloscope to measure the 110 volts AC in a home wall outlet if so how is it done safely to avoid damage to the oscilloscope?
The first thing to consider in measuring the line voltage of a home wall outlet is the oscilloscope probe voltage rating. Most high-impedance probes have a resistance of one M…egohm of greater and will withstand peak voltages in excess of 200 Volts, but it pays to make sure that you do not damage the resistor within the probe. The next item of concern is the current flowing in the power line ground. If you have a ground current protected outlet, then it will be safe from dangerous ground currents. It will also limit the voltage errors produced by any circulating ground currents. As is the case for many instruments, the metal case is generally tied to the line common through a small capacitor, so the ground current can produce a small voltage between the case and line common. That is the purpose of using a line current interrupter for protection. Do NOT connect the oscilloscope ground lead to the line socket. If you connect it to the wrong pin, then the case can be at a high enough voltage to cause shock. Better to be on the safe side. Keep in mind that the voltage is rating in RMS (root-mean-square) volts and not peak or average volts. Therefore, the sine wave peak is 1.414 (square root of 2) times the RMS voltage. Conversely, the RMS voltage the peak voltage divided by 1.414.

Power (Watts) = Current (Amps) * Voltage Power = 22Amps * 240 Volts Power = 5,280 Watts 5280
