How to use a 120V USA microwave in India where the voltage is 240V?

Answer 1

Microwaves use a lot of current. A transformer that could handle this load would be expensive and large. Plus it would draw an equal amount of current as the microwave itself. However, unless this microwave is designed to operate at 50 or 60Hz it probably wont work even if the correct voltage is applied, since the AC frequency in India is 50Hz, and many microwaves (and also TVs and alarm clocks) are frequency sensitive. There is no economical way to convert the frequency. Considering the cost of the transformer vs the cost of a new microwave, plus the chance that it wont work anyway, it would be best to buy a new microwave.

If you did get it working, if you tried to cook something for 6 minutes it would only cook for five. ;)

The AC voltage in the U. S. is a hundred and twenty and in the united kingdom 240. possibly those are much less confusing subdivisions of the voltage used on power strains. the flexibility strains carry hundreds of volts as a results of fact they lose some around the strains to the substations which knock all of it the way down to a hundred and twenty/240. the U. S. use a hundred and twenty because it somewhat is safer and to that end has 2 pins and no earth. The 240v/120v must be intense to power intense powered contraptions like easy bulbs,warmers,kettles - as a results of fact the flexibility - W = IV with the comparable modern,shrink the voltage you shrink the flexibility - with a view to warmth or easy something the voltage must be intense adequate. In different contraptions which incorporate HiFi - the voltage is knocked down back to 12-20 volts (comparable with desktops which use 5/12 v) - as a results of fact much less power is mandatory to run the electronics. when you consider that i'm engaged on recyclable power on the 2d - the situation is that this: maximum digital contraptions ought to evade power loss in the transformer by way of being offered with 12v from a photograph voltaic source immediately- when you consider that we count number on well-known power era we use hundreds of volts which lose power on the substation and lose power back in transformers. community power production in photograph voltaic cells ability you canchronic maximum electronics direct with 12/24 volts and evade power loss. So the fundamental answer on your query is approximately loss of power in power strains and substations. The convention approximately a hundred and twenty/240 i assume is to do with the voltage produced on the well-known source. yet you're appropriate - it ought to be yet another voltage.

Answer 3

A ppower convertor is required. But do not get into this hassel. Buy a microwave oven in India. A good one should not be more than Rs. 10000 .

Answer 4

A radio shack converter works best. But u can use it on only one appliance at a time.

Answer 5

use a converter input 240 v out put 120 v

Answer 6

radio shack sell converters
but I don't know about for a microwave thats
pretty heavy duty.

Answer 7

You need a stepdown transformer
