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.
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 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.
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?
Assume the supply as DC (Only resistance given) Voltage drop = 10X10X0.12 = 12V (approx)

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

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.
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.

If you plug an electric toaster rated at 110-v into a 220-v outlet what will the outlet current in the toaster be?
It doesnt matter you will smoke it. The current in a resistive circuit is proportional to the voltage. If the voltage doubles and the resistance is the same (elements) the current will double and burn up both the elements and the toaster wiring. Look up "ohms law" for current voltage and resistance effects. Don't try it..
What is a male plug?
It is a device inserted to a convinience outlet to conduct electric current. A flat cord is attached to it on one end and the other end is to a current consuming instrument or appliance... :)
How many volts come out of a average outlet?
Voltage does not come out of an average home outlet under normal circumstances.In North America the common potential voltage is 120 volts and is always at the receptacle as long as the circuit is energized. When an electrical device is plugged into the receptacle, through the device's connected cord, this brings the potential supply voltage to the electrical device.When the device is turned on a current (amperage) will flow, governed by the resistance of the device. If it is a lamp, it will become bright. If it is a radio you will hear sounds.When you unplug the electrical device from the receptacle, the device will stop operating but the voltage potential will still remain on the "hot" side of the receptacle's blade contact point.
What is an outlet item?
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."
