In the U.S. you should be using 110-115V.
110
115V
115 V in united states and 220 v in other countries
The 110VAC to 125VAC range (not the 220VAC to 250VAC range).
The 110VAC to 125VAC range (not the 220VAC to 250VAC range).
It depends on the device. The US runs at half the voltage of Europe (110/120VAC vs 220/240 VAC). The device to be plugged in should state what input voltage range it can tolerate, or, in the case of a computer, will have a 110/220 switch on the back of the power supply.
There is no formula to convert voltage. Voltage is universal.
US Voltage is 120 V @ 60 Hz.Ecuador Voltage is 120 V @ 60 Hz.They're compatible, the plugs are also the same.
Barbados has a voltage of 115 V @ 50 Hz (vs 120 V @ 60 Hz in the US and Canada). You should have no compatibility problems though.
Now is a great time to teach your child how to appropriately use the computer. Set firm limits with him, and only allow him to use the computer during a specific time frame.
the voltage and frequency are 110v and 50(or)60hz because the devices which are invented in us are work at that voltage and it is efficient for that devices.
The power supply converts the high voltage (e.g. 120VAC in US, 240VAC in Europe) alternating current house electricity supply down to the various different low voltage direct current supplies needed by different devices that make up the computer. These low voltage direct current supplies are tightly regulated in the power supply circuitry to prevent transients in the house electric supply from perturbing the computer's electronics as well as to compensate for variations in power demand as the different devices that make up the computer operate.
Check the curler, it should say on the side somewhere the acceptable voltage, For US that would be 110V, but you may see 100-220V, in which case it will be safe on UK Voltage, (220V) You will need a plug adaptor though, but not a voltage adaptor
It depends on the country as to which voltage is used for industrial purposes. In the US, for welding for example, voltage may be 480 volts. The frequency in the US is 60 Hertz.
The meter should be on the AC scale. In Canada and US the reading should be 240 on the outside blade holes and 120 volt from the outside blade holes to the center blade hole. The U shaped pin is the ground. No voltage from it to the center pin.
