What would you like to do?

# If you had a multimeter and plugged it into a 120V wall outlet what electrical current would it read?

# If an electric clothes dryer has a resistance of 12 ohms and it draws 20amps of current what is the voltage in volts of the wall outlet that it is plugged into?

We know that Voltage = Current x Resistance, so if E = I x R, then E = 20 x 12 = 240 volts, and the dryer must be plugged into a 240 volt outlet.

# An electric clothes dryer has a resistance of 12 ohm it draws 20 a of current what is the voltage in volts of the wall outlet that it is plugged into?

240 volts, 12 * 20 = 240.

# Can you plug a 115V appliance into a 120V outlet?

For residential service 110V, 115V, 117V, 120V, and 125V are all functionally the same. Electric companies have been slowly increasing the line voltage over the last 100 years… to cope with increased loads. That is where these different voltages come from. The tolerance is generally +/-10%. That's +/- 11.5 volts in this case. So, a 115VAC appliance will run between 103.5 and 126.5VAC. The short answer is yes. 110V appliances can work with up to 130V without being burnt, additionally, 220V appliances can work with up to 240V without being burnt.

# Can you plug a 240V appliance into a 120V outlet?

No. The device will only have half the voltage it needs and will not operate properly. Follow the ratings on the device. The pin configuration of the 240 volt receptacle is d…ifferent from a 120 volt pin configuration. This is a safety factor to prevent the wrong voltage being applied to the wrong devices.

# Can you plug in a 120V appliance into a 110V outlet?

Yes, they are functionally the same. A little deeper Not only are they functionally the same, but they are truly one and the same thing. That which some people c…all a 110 volt line and what some call a 120 volt line are provide by the same equipment. The difference in the name is based on what was the standard voltage at the time the person speaking learned what to call it. Presently, it is not uncommon to find 125 volts and 130 volts [and more] at a receptacle outlet. The upward ratcheting line voltage is the answer power companies use to address ever-increasing demand. For more information see the answer to the Related Question shown below.

# Can you plug an 110V appliance in a 120v outlet?

Any 110 volt appliance is designed to be plugged into a 120 volt outlet. 120 volt outlets generally supply between 105 and 120 volts.

# How much current does a 60 watt light bulb draw from a 120v wall outlet?

Using the Electrical Power Law, which is: The current (measured in amps) equals the power (measured in watts) divided by the potential difference (measured in volts) So a …light bulb designed to use 60 watts of power when supplied with 120 volts must draw 60 watts divided by 120 volts, which is a current of 0.5 amps. The same answer could be expressed in a few different ways: 500 milliwatts 500 mW "1/2 an amp" !

# Can you plug 120v plug into 240v outlet?

Answer Hi, They're shaped differently, so probably not. Besides, plugging in a 120 volt device into a 240 volt power source would be disastrous to the device a…nd not a good idea. Hope this helps, Cubby

# How do you test a wall outlet with a multimeter?

Answer Put the meter on AC Volts, 200V range. For residential US service you should have 120V between hot and neutral, 120V between hot and ground, and 0V betwe…en neutral and ground. Remember: narrow prong is hot, wide prong is neutral, round prong is ground. Don't set your meter to current or you will zap it. Reisitance shouldn't damage it, but the reading will be worthless. (If you don't know what you are testing for or how to use your tool, should you really be sticking things in a wall outlet?)

# If an electric clothes dryer has a resistance of 16 ohms and it draws 15amps of current what is the voltage in volts of the wall outlet that it is plugged into?

Ohm's Law: Voltage = resistance times current 16 ohms times 15 amperes = 240 volts.

# Can an electric stove plug be converted to a regular 120V outlet and if so how?

The typical electric stove (range) operates on a plug that supplies 220 volts AC to the stove. Some parts of the stove operate on 110 volts AC. The oven light for instance…. The standard range plug consist of two separate 110 volt lines, which add up to 220 volts. It also has a third line that is referred to as the "common" line. It won't work without it. You could open the plug, attach a wire to one of the 110 volt lines and another from the common to a standard 110 volt plug. This however is dangerous and you should be well aware of what you are doing. Most modern wiring also has another wire which is usually a bare conductor which is called a "ground", therefore the 3 prongs on a standard 110 volt plug. It is safest to have the third wire in place otherwise electric shock and injury may occur. Kill the power before attempting any of the above as electricity properly grounded through you could kill you. The heating elements on the stove will not work on 110 volts so if you are looking to save power you are right because it won't use any. The stove simply will not work, which would be a savings. For safety, you will also need to disconnect the two stove conductors at the distribution panel breaker and replace it with a 15-Amp or 20-Amp breaker to protect the 110 outlet and any devices plugged into it. With some effort, you could First, I assume you're comfortable working around electrical panels. If you're not, PLEASE get an electrician to do this! There are two things that really need to be done to make this work. First is at the panel. Right now, there is a double-pole 50-amp breaker serving that outlet. It is connected to the outlet with 6/3 AWG wire--6 gauge, 3 conductors and a ground. No 110-volt outlet in the world can deal with 50 amps of current. Turn off the main breaker, open your panel and replace that 50-amp double-pole breaker with two 20-amp single breakers. Close up the panel, and you're done. Next is at the outlet. You will need: two 20-amp duplex receptacles, the deepest two-gang old work box they've got at the store, some nice fat wire nuts, a two-gang cover plate, and some 10-gauge solid wire: a foot of red, a foot of black, two feet of white and two feet of uninsulated. You have to pigtail 10 AWG (American Wire Gauge--how solid wire is sized) to the present 6 AWG because 6 AWG won't fit in a 20-amp receptacle. You have to twist the wires together to make the connections, and there's only one good way to do it--hold two wires parallel to each other, lock them together with vise grips and twist them with another pair of pliers. Anyway, put single pigtails on the red and black, and double pigtails on the white and bare. Hook them to your receptacles and seal the box up. You now have a pair of outlets that won't ever give you trouble.

# Can you plug a 240V amplifier into a 120V outlet?

No, you can not plug a 240 volt amplifier into a 120 volt outlet. That said there are a number of step-up transformers available that will convert 110V to 220V - that's the si…mplest way to do it. You should make sure the transformer is rated at many times the power of your amplifier, because of inefficiencies in the amplifier. Look on your amplifier to see how many amps it uses at 220V. Double that number for going to 110 and add 20% more amps as a conversion margin. Take that number and multiply it by 110 to get the watts you need to supply. Size the transformer accordingly. eg. 5 amps @ 220V 5 amps * 2 = 10 amps 10*20% = 2 amps Total amps = 12 amps 12 amps*110 = 1320 watts In this example a transformer rated at or above the calculated wattage is recommended.
