You need a step-up transformer.
No country in the world uses 138 volts. They use 100, 110, 115, 120, 127, 210, 220, & 240.
It depends which country you are in. Some countries use 115 Volts AC for household supplies, some use 220, 230 or 240 Volts AC. See the link below for a list of which countries use which voltage.
The higher voltage need more resistance, from the formula W = V2 / R. That means R = V2 / W. So 220 v 100 W is 484 ohms, while 115 v 100 W is 132¼ ohms.
You don't. Voltages are a nominal rating. 110 volts is within the nominal range at this potential. The voltage centre line is 115 volts. Utility companies are mandated to keep voltages locked within 5% of a centre line voltage. This means that it could be as high as 115 + 5% = 120.75 volts and as low as 115 - 5% = 109.25 volts
Divide the watts by the volts, so 32 / 115 is the answer in amps.
Each voltage has a range and devices rated in that range will all work . The 110 to 120 volts is one range of voltages. The 220 to 240 is another range of voltages. The reason there is a range of voltages is to help the utility company out. They are mandated to keep the voltages within a + or - 5% range of a set voltage. Because there are loads coming on line and loads dropping off line the voltage fluctuates. Using a base voltage of 115 and 230 volts means that the voltage can rise by 115 +5% = 121 volts and drop by 115 - 5% = 109 volts. In the 230 volt range the voltage can rise by 230 + 5% = 241 and drop by 230 - 5% = 219 volts. As you see they are still in the usable voltage ranges.
Two wires are needed for 220 volts.
Does this air conditioner require 220 volts?
If the Peak to neutral voltage is 220 volts, the root mean square voltage is 155.6 volts (sqrt(220)).
220 volts, 110 volts, 440 volts, 400 volts, AC or DC voltage. High voltage like - 220 KV, 400 KV, etc
220 VAC stands for 220 Volts Alternating Current. It represents the voltage and type of electrical current commonly used in residential and commercial settings for powering various devices and appliances.
The formula you are looking for is W = Amps x Volts.
