How come in other parts of the globe, they uses 110 volts of electricity while in most parts of Asia we uses 220 volts?

It's all about money.We need bigger cables in 110volts system to deliver same power in order to reduce line loss which is also money.

The countries using 110 volts will pay too much to change the system to 220 volts so they keep it ,in addition the 110 volts is more safe ( in case of electric shock ) than 220 volts .

It's for safety reasons....110 volts will shock you less then 220 will. Every body has a current resistance. The formula is U=RI where U is the voltage, R resistance and I current intenisty. Well I=U/R, if your body has a resistance of 1Kohm and the voltage is 110, you get 0,11amps while if the voltage is 220 you get 0,22amps. 110V combined with your resistance means that you are less likely to be killed. That's why some countries use 110V

I will say in some rural or remote places, higher the voltage is better because it will help provide electricity to further places. With lower voltage, the power lost to the cables will be greater.

In the U.S. it is 110v @ 60hertz (cycles per second). In England the frequency is 50 hertz. There never will be a standard.

However it is easier to transmit high voltage on transmission wires. It sounds like in your country they don't use transformers to step the voltage down to 110v at the houses.

standard modules contains image voltaic cells in series, each and each image voltaic cellular (monocrystaline) supplies approximately 0.6 v, and short circuit modern-day of three.4A, so which you upload the voltages of each and every of the cells to get the output voltage, and it is going to likely be approximately 14v it is sufficient to cost one 12v-batter. each and every each and every now and then, inorder to get extra output modern-day (i.e. potential) , extra advantageous than one module might nicely be conncted in parallel you get 6.8A at 14v.

There is no reason not to have a universal household wiring standard. But we dont.

Buy a110V/220V transformer.

the same reason we use foot and they use meter
