# 110V to 220V

#### Why different countries have different voltage?

##### Friday, May 20, 2016

Why voltage in some countries is 220V (208V, 230V, 240V) and 110V (100V, 120V) in some countries? Why can't we have the same Voltage and what are the Pros & Cons of using 110 V or 220 V in their Respective regions?

110V or 220V, Each system has its own advantages and disadvantages, so each country before designing a system Engineers sat down agreed on factors and concluded on which system to use taking in account:
Their ...

#### What happens if plug an 110V appliance in 220V socket?

##### Wednesday, December 31, 2014

It depends upon the nature of the appliance but generally speaking if the voltage is too high it draws too much current and burns out, if the voltage is too low it draws too little current and/or does not perform to its rating. The mathematical reference is Ohm's Law and the Power Triangle.

If you plug an 110V appliance in 220V outlet (same as 120v to 230v, 240v) you can only hope that some protection device disconnects the power to the appliance.
Otherwise: ...

#### Earth fault in 220V to 110V converters

##### Friday, December 19, 2014

We have 220 DC (UPS) distributions board supplying 220v/110v converters and 220/24v converters, only in the 110 dc board we get a frequent earth fault alarms in DCS (every 30 min not a permanent ) the problem that we can not localize which feeders are making the fault due to the big number (more than 100 solenoids valve are supplied ) and when we make the voltage monitoring all of them are indicating an unbalance value between + and ...

#### Convert single phase to three phase power supply

##### Tuesday, December 2, 2014

In the design work for a project to convert from single phase to three-phase AC power supply, where should we start implementation of the project? What problems might face in converting single phase to three phase power and how to avoid them?

We can change 1 phase power to 3 phase like any other power project; determine ...

#### How to convert 110v/120v 60Hz to 220v/230v/240v 50Hz

##### Tuesday, October 14, 2014

Home appliances, like TV, speaker, lights, may work with both 50 Hertz and 60 Hertz, but some appliances especially with electric motor inside it, like air conditioner, fridge, can only work with 50Hz or 60Hz. If a 50 Hz motor working on 60 Hz power system, the motor speed will be 20% faster, then cause over temperature and shorten its service life.

We all know, most European and Asia countries powe ...
