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:
A multimeter cannot test dc current with a clamp on meter (there is no frequency in dc to create a field)
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.
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:
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.
Almost all sewing machines, with the exception of vintage hand crank machines, need to be plugged into an electrical outlet.
Generally, no. We usually try to avoid having a lot of things plugged into one outlet, which is the usual meaning of "octopus connection" when we talk about things electrical. If we get a lot of stuff plugged into one outlet or a single outlet strip, we could approach (or exceed) the current rating on the outlet and end up tripping a circuit breaker. Less things plugged in is better.
It is plugged into an electrical outlet without a transformer
A PS3 must be plugged in to an electric outlet
No, if nothing is plugged in pulling current then you are using no electricity by leaving the switch in the on position.
A unidirectional current controller device is a type of electrical on/off switch. In order for an item to work that is plugged into a particular outlet, the switch must be in the on position. It is like having lamps plugged into outlets that are controlled by only one switch.
Electrical energy, usually. In general, any device plugged into an electrical outlet uses electrical energy.
the form of energy changes and the total of energy increases
Yes, an appliance that is 115 volts 15 amps can be plugged into a normal household electrical outlet in the Untied States of America, also available in Canada. LOL
Electromagnetic energy, electrical lighting is one of the many ways electrical energy is used. Electric current flows in these devices when they are connected to batteries or plugged into an electric outlet. An electric device uses the electrical energy provided by the current flowing in the device.
Uh, because you left the switch on for what you had plugged in to the outlet.
These days you can get deevices called voltmeters that if plugged into your electrical outlet, tells you the current flowing from the socket. You can know ot in Amperes, watts and volts.
The fuse is what restricts how much current you can draw from an outlet. If you have the wrong fuse you can draw more power than intended from an outlet - but only if the appliance plugged in can use it up. To get too much power out of an outlet, with a suitable appliance plugged in, then you also have to have a higher voltage in the outlet. And for that to happen, something has to be seriously wrong higher upp in the supply chain.
Nothing YET- but when the toaster is turned on, electrical energy is changed to heat (and a little light)
a shorted out outlet can cause a backfeed on the white wire, an open circuit on the white wire with and electrical appliance plugged in to an outlet can cause the same type of backfeed
Either the supply or the multimeter is faulty.
An electrical cord is provided for just that purpose and when plugged into an electrical outlet, the battery charging light will come on. After the unit is fully charged, the Battery Fully Charged light comes on and you can unplug from electrical outlet and use anywhere you need it.
The voltage is always present, but no current is flowing.
R = Volts / Amps
Yes, Unless your an Eco Freak. I keep my Wii plugged in all the time. It wastes VERY VERY little power.
Yes, a space heater can be plugged into any outlet. Depending on what else is drawing current on the circuit will govern whether the circuit will trip or not. If the heater is plugged in and the circuit does not trip it can be left plugged as long as it is needed. If the heater trips after a few seconds, then try another outlet.
The definition of an outlet in Article 100 of the National Electrical Code book (US) is: "Outlet. A point on the wiring system at which current is taken to supply utilization equipment." You can have a receptacle outlet, lighting outlet, or some other hardwired equipment outlet. <<>> The definition of an outlet in Section 0 (Object, Scope and Definitions) of the Canadian Electrical Code book is: "Outlet. A point in the wiring installation at which current is taken to supply utilization equipment."
Yes, it can be and there is no problem at all Because most of the electrical appliances are made to work on 220v - 240v so it can also be plugged into a 240v outlet.
Unless it is defective, it is not dangerous to leave a phone charger plugged in an electrical outlet. But the transformer and circuit within the charger still draw current and dissipate a small amount of heat, so it is considered a wasteful use of electricity (and thereby damaging to the environment) to leave it plugged in when it is not charging a cell phone.
This is a really bad idea. The current will double and bad things can happen.
