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.

How do you figure out an appliance's power consumption if you have the voltage and Frequency and Current?
You just need the voltage and the current. Watts = Amps x Volts.
How do you find the current draw of an electrical circuit if you do not know the voltage and wattage of the device?
Basically if you know the Voltage supply and the power used by an appliance then you use the formula for power which is Power = Volts x Amps. Rearrange so Amps (current) = Power / Volts If power was 2400 Watts and Volts was 240 the Current would be 2400 / 240 = 10 Amps
What is a resistance of the appliance If 24 amps of current flows through an appliance connected to a 120 v circuit.?
Let R be the resistance, V the voltage, and I the current R = V / I R = 120 / 24 R = 5 ohm
How do you convert watts into amperes?
To convert watts into amperes you divide the circuit voltage into the watts. Amps = Watts/Volts. <<>> Converting Watts to Amps The conversion of Watts to Amps is governed by the equation Amps = Watts/Volts For example 12 watts/12 volts = 1 amp Converting Amps to Watts The conversion of Amps to Watts is governed by the equation Watts = Amps x Volts For example 1 amp * 110 volts = 110 watts Converting Watts to Volts The conversion of Watts to Volts is governed by the equation Volts = Watts/Amps For example 100 watts/10 amps = 10 volts Converting Volts to Watts The conversion of Volts to Watts is governed by the equation Watts = Amps x Volts For example 1.5 amps * 12 volts = 18 watts Converting Volts to Amps at fixed wattage The conversion of Volts to Amps is governed by the equations Amps = Watts/Volts For example 120 watts/110 volts = 1.09 amps Converting Amps to Volts at fixed wattage The conversion of Amps to Volts is governed by the equation Volts = Watts/Amps For Example, 48 watts / 12 Amps = 4 Volts Explanation Amps are how many electrons flow past a certain point per second. Volts is a measure of how much force that each electron is under. Think of water in a hose. A gallon a minute (think amps) just dribbles out if it is under low pressure (think low voltage). But if you restrict the end of the hose, letting the pressure build up, the water can have more power (like watts), even though it is still only one gallon a minute. In fact the power can grow enormous as the pressure builds, to the point that a water knife can cut a sheet of glass. In the same manner as the voltage is increased a small amount of current can turn into a lot of watts.
If an appliance draws 10 amps and the line voltage is 110 volts the power consumed is?
The equation that you are looking for is Watts = Amps x Volts. Power is consumed at that rate over a time constant. You are billed by the electrical utility company by the kWh. 1000 watts are equal to 1 kW.
Can a device requiring 12 volts and 3 amps run with an adapter providing 12 volts and 2 amps?
No. Your power supply must be able to supply rated voltage (12 volts) and rated current (3 amps).
I have my 120 volt appliance and in Philippines we have 240 volt. Can a 110 - 250 volt adapter be used?
An adapter can be used. Make sure that the adapter that you use is of a capacity that it can produce the amperage that your appliance needs. An adapter too small will burn itself open and will be of no use to anyone. Remember; Watts = Amps x Volts.
Does 50 amps rated at 240 volts equal 100 amps rated at 120 volts?
When you multiply amps x volts the product is watts. Using this formula W = Amps x Volts should give you your answer.
A 60 Watt appliance is plugged into a 120 Volt AC outlet How much current is the appliance drawing when it is turned on?
Amps (current) times volts = watts. so watts divided by volts = current (Amps). i.e.- 0.5 Amps.
What is the voltage of an appliance that has a current of 3 amps and a resistance of 4 ohms?
12 volts.
What is the difference between a 9v 300mA Adapter and a 12v 300mA Adapter?
difference is 2.7 amperes in numbers will be 12 volts 3 amps and the other will be 12 volts .3 amps
If an appliance draws 10 amps and the line voltage is 110 volts the power consumption is?
Power = volts times amps, so an appliance drawing 10 amps at a line voltage of 110 volts is consuming 1,100 watts. Keep in mind, however, that in a non purely resistive load, the phase angle of amps to volts might not be zero degrees, so the calculation becomes more complex, and depends on power factor, or phase angle.
How many amps can handle in 12 volts a 600 volts 15 amps rated terminal bar?
The terminal strip's rating is 15 amps at 600 volts. It does not matter what the voltage is up to 600 volts, the maximum amperage allowed on the strip is 15 amps. It could be 15 amps at 12 volts or 15 amps at 600 volts or any voltage in between.
Can an appliance that is 115 volts 15 amps be plugged into a normal household electrical outlet in the untied states?
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
What is a measure of the electric power of a appliance?
The watt is the unit of power. For electricity, watts = volts x amps.
How much current is drawn when an appliance rated at 795 W is plugged into a 120 V wall outlet?
it is 795 divided by 120. <<>> The formula you are looking for is I = W/E, Amps = Watts/Volts.
What size wire to carry 8 amps at 120 volts?
A # 14 copper conductor will be fine to carry 8 amps at 120 volts. This size conductor is rated at 15 amps.
