What else can I help you with?
A microwave oven has a resistance of 24 ohms It draws 5 A of current What is the voltage in volts of the wall outlet that it is plugged into?
Ohm's Law says Voltage = Current x Resistance V = 5 x 24 = 120 V.
What happens to the overall resistance of a circuit when too many appliances are connected across a 120 V outlet?
This is a very technical electrical question that may be difficult to understand without further study. But adding appliances to an outlet is the same as adding resistance in parallel. Adding resistance in parallel, the resistance of the circuit goes down. That is why you get more current flow. By contrast, adding resistance in series increases the resistance of the circuit and therefore reduces current, all else being equal.
What changes alternating current into direct current?
Yes but is somewhat complicated to get good level DC from an AC source.================================Answer #1.5 :All electronic devices operate on DC ... radios, TVs, computers, stereos, etc.If the device plugs into the wall outlet for power to operate, then the AC fromthe wall outlet is used to produce DC internally to run the device.
What is unidirectional current controller?
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.
A desktop computer and monitor together draw about 0.6 A of current They plug into a wall outlet that is 120 V What is the resistance in ohms of the computermonitor combination?
To find the resistance in a circuit, use the equation R = V/I, where R is the resistence in ohms, V is the voltage, and I is the current in amps. Therefore, your equation is R = 120/0.6. Therefore, the resistance is 200 ohms. Hope this helps

What type of electrical outlet is required for a device that needs to be plugged into a 240V 50 amp plug?
The device requires a NEMA 6-50 outlet, which is a specific type of electrical outlet that can provide 240 volts and handle up to 50 amps of current.
What are the specific electrical requirements for a device that needs to be plugged into a 10-30R outlet?
A device that needs to be plugged into a 10-30R outlet requires a 240-volt electrical supply with a maximum current rating of 30 amps.
Why can't I plug this device into the outlet?
There could be several reasons why you can't plug the device into the outlet. It could be due to a faulty outlet, a damaged plug on the device, or the outlet not providing power. It's important to check the outlet and the device to determine the exact reason.
How much current flows through a toaster with a resistance of 20 ohms when it is connected to a 110 volt outlet?
Ohm's Law Volts = Current x Resistance Amps = V / R 110 / 20 = 5.5 Amps
Does a wall outlet control current voltage or resistance?
None of the above. It is only a place to connect to the power grid. There is a bit more to the answer than this, but here it is. There is voltage at the outlet. Voltage is the ability to move electrons (current). What you plug in has "resistance" to it. It (the appliance) is designed to work at that voltage, so it has an amount of "resistance" associated with it owing to its construction. The combination of the voltage present and the "resistance" plugged into the voltage source will determine the amount of current that will be drawn. The fundamental relationship between voltage, resistance and current is that voltage (which is electromotive force and will cause current to flow if given a complete circuit to work through) equals current (the actual moving electrons, or the amount of moving electrons) times resistance (the limiting factor in things - the nature of the material in the circuit and the configuration of the material as regards how well it will conduct electric current that is changing direction, is alternating). Breakers or fuses in the distribution panel provide a current limiting safety feature. But the electrical outlet itself controls nothing that is plugged into it. In the power grid, the voltage is AC (alternating current), and a lot of the things we plug in are inductive (like electric motors) and not "resistive" as stated above. The term "resistive" was used to convey basic meaning. This is a basic question. Don't trash this answer with a lot of highly technical mumbo jumbo. Save that for the engineering section. See you there.
A microwave oven has a resistance of 24 ohms It draws 5 A of current What is the voltage in volts of the wall outlet that it is plugged into?
Ohm's Law says Voltage = Current x Resistance V = 5 x 24 = 120 V.
Can you plug in a 12 vdc fan to house current outlet?
If you do it will burn the winding immediately and make the fan inoperable. So, No, don't plug in ANY 12VDC device into a 120 outlet.

An electric clothes dryer has a resistance of 16 ohms It draws 15 A 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.

The wiring in the wall of your house to and from an outlet has a total resistance of typically 0.12 ohms suppose a device plugged into a 120 V outlet draws 10 A of current What is the voltage drop?
The voltage drop across the wiring in the wall is calculated using Ohm's Law: V = I * R, where V is the voltage drop, I is the current, and R is the resistance. Plugging in the values, V = 10 A * 0.12 ohms = 1.2 V. Therefore, the voltage drop across the wiring in the wall is 1.2 V.
