How does voltage change across an appliance in a parallel circuit?
With the minor voltage loss in the wiring, the voltage drop across a single appliance is the total voltage in the circuit, and doesn't change when more devices are added in parallel.
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
What is the power of an electrical appliance?
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
What happens to the output in terms of real power of a generator when you change the voltage and frequency say from 220v 50Hz to 110v 60Hz?
The voltage and frequency ARE the output of the generator. If you change the fuel to the generator, it will change speed, and the voltage will change. Less fuel = less speed = lower frequency = lower voltage.
How many volts in 1200 watts?
Wattage is unit of power which is the product of Voltage in V and Current in Amps. If you know the current drawn by the appliance with 1200 Watts then you can calculate the Voltage = Power/ Current. For eg. if the current drawn by the appliance is 100A then the voltage is 1200/100 i.e. 12 Volts.

Can you use any 220 volt adaptor on a 110 volt appliance?
No. 220V adaptor can't control the output voltage, 110V appliance will be fry. Use instrument transformer or voltage regulator instead.
Can you use a 6 volt adapter on a 4.5 volt appliance?
No, the voltage from the adapter should match the voltage required by the appliance.
Can you plug a 115V small American appliance into 240V outlet in Australia?
Its not the appliance that needs modification but the electrical delivery. You need a converter/transformer or adapter to change the way power is fed to the appliance. See the link provided for more explanation.
Will the power consumed by an electrical appliance increase with a reduction of applied voltage?
Power consumed by an electrical appliance will increase with a reduction of applied voltage.
Can 120V appliance work with 220V?
120V appliance will not work on 220V. Use an instrument transformer or voltage regulator to adjust the high voltage to the desired level.
Is there a step up transformer that I can purchase to use a 220V 50Hz 13A kitchen appliance in a regular kitchen in the US?
A transformer will not change the frequency. 50 Hertz in 50 Hertz out. 60 Hertz in 60 Hertz out. Transformers main purpose is to change one voltage value to different voltage value. Depending on what the kitchen appliance is and whether it has a motor involved in its operation, the appliance could be connected to the 240 volt North American distribution supply. If the appliance was identified, an answer of yes or no could be supplied.
Can you buy a 120v appliance and use it with a 220v outlet?
A high voltage will certainly damage a low voltage appliance and perhaps set fire to other things nearby.
What appliance has DC voltage?
A laptop computer requires DC.
If an adaptor is marked with output 12v dc and 2000mA does this mean the appliance draws 2amps when in use?
Yes and No. You have three types of adaptors: constant current with variable voltage output. constant voltage with variable current output. constant voltage with constant current output. What you are talking about is the latter. This means that the adaptor was created for a specific appliance requiring 12V/2A, which it will indeed use. Heavier appliance will not draw enough current/voltage and will malfunction. Lighter appliance will draw too much current/voltage and will overload/shortcircuit.
What is the power of an electrical appliance?
It depends on the appliance. All appliances are required to have a 'nameplate' which contains information on their power and voltage ratings.
Can you use ac dc adapter of 12 volts and 2 amps for an appliance rated for 7.5 volts and 1.8 amps?
To use an adapter of this sort, its rated voltage must match the rated voltage of the appliance, and its rated current must exceed that of the appliance. So, in your example, the rated voltage is too high to be used with your appliance.
