# 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.

# What type of current comes from the outlets in your home?

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.

# What kind of current comes from the wall outlet?

I know that it may be electrical current. yep it is thx i got a 96 on my test :) k.m

# Can you use a compass to detect the currents in wires in the walls near light switches in your home?

Yes, the needle would point perpendicular to the wire, and parallels to the magnetic lines of the wire. Another answer The above answer would be correct IF you wer…e dealing with a DC circuit AND there was a load on the circuit, but house wiring uses Alternating Current, and the compass needle would attempt to reverse directions at the rate of 60 cycles per second. Effectively, the needle would simply act strange when it's near house wiring, IF there is a current load on the wire. ++ To add to that, use a proper cable-locator, not a compass.

# Wall outlets use what kind of current?

alternating current

# An electric clothes dryer draws 20 A of current from a 240 V wall outlet how much power in watts does it use?

The formula you are looking for is W = A x V. Multiplying the amperage A in amps times the voltage V in volts provides the power W in watts (joules/sec).

# An electric clothes dryer draws 22 A of current from a 240 V wall outlet How much power in watts does it use?

An electric clothes dryer demands 22A from a 240V outlet at approximately 90% Power Factor. The power demand on the outlet should be about 240V x 22A x 0.9 = 4.75 kW. The acti…ve components in an electric clothes dryer are the heating element (100% PF) and the electric motor that turns the tumbler (70-80% PF). The formula you are looking for is W = I x E. (W is watts, I is current in amps, E is volts)

# 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

# Does measuring the the wall outlet voltage give you the full load measurement?

A: measuring the wall outlet will tell the potential in volts available but not the power capability. If a load is applied then that voltage shell tell you the wall outlet cap…ability under load B: mostly correct, the measurement of the outlet under load of an item plugged in will tell you the load drawn by that item, but not the load capacity of the outlet, that is found in you power box by what level fuse is in that circuit and what else is running on that same circuit. most outlets have a 10 amp rating, some have 15 amps some have 20 amps, though most appliances do not draw more than 10 amps anyway.

# A meter used to measure energy consumed is called a?

Won't it be the Wattmeter, for 1W = 1Joule/second? The domestic electricity meter is a kW/hr meter.

# Does Canada have the same outlets as the us?

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.

# Can you use Netflix on two computers in the same house using the same account?

As long as both computers are able to run the software that NetFlix uses. Yes, an individual can run netflix on any number of computers under the same account.

# 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.
