Not exactly. Singapore uses types G, C and M while the UK only uses G. So, there is a possibility that you will find types C or M instead of type G.
Yes, Irish plug sockets are the same as UK plug sockets. Both countries use the Type G plug, which has three rectangular prongs in a triangular pattern.
To use UK appliances in Singapore, you will likely need a plug adapter to fit the UK plug into a Singapore power outlet. However, be sure to check the voltage requirements of your UK appliances as Singapore uses 230V while the UK uses 240V. Some appliances may be dual voltage or have adapters to adjust for voltage differences. If not, you may need a voltage converter to ensure compatibility.
Yes they can. You just need an adapter to plug them in as the electrical plug sockets are different in the UK than in other parts of Europe.
The whole of Europe, including the UK, uses the same voltage for mains electricity, 220 V 50 Hz. But the plugs and sockets are different in different countries. You will need to either change the plug or get a plug adaptor.
they only use electricity when an appliance is plugged in and switched on
Yes
It would work, however you would need to obtain a plug adapter as power sockets in mainland Europe are primarily two pin, where as the UK uses 3 pin sockets.
Yes, Ireland uses the same type of plug as the UK, which is the Type G plug.
No, the Ireland plug is different from the UK plug. Ireland uses a Type G plug, while the UK uses a Type G plug.
yes, obviously it will be the same.
Yes, but you'll probably need to get a new charger for it to plug into the sockets in the UK. Games bought in the UK will work on a USA-version Nintendo DS.
no. North America uses a 110 volt household current, UK. uses 220 volts. You would need a transformer to step down the current. The plug lay-out is also different.
