Answer for countries in Europe and other world areas running a 50 Hz supply service.
A 3 phase service allows three times the power to be supplied for a given conductor (cable) size. Each phase is at 230V to earth/neutral and 400V between phases. Common single phase standard domestic installations rated at 100 amps provide a total aailable power of 100A x 230V = 23,000 watts. (23 kilowatts)
Using the same size cable, a 100A three-phase installation has three service lines, each rated at 100A, making a total of 300A, at the same voltage, meaning that the total power available is 300A x 230 v = 69,000 watts. (69 kW) .
Alternatively the three-phase load can be connected between the live wires (delta connection), with 400 v across the lines. With the same 100 amp current in the supply lines, the current in each of the three loads is now 58 amps and the maximum power remains 69 kW.
This amount of power is often required for industrial and/or commercial installations, or perhaps domestic installations where a heavy load is connected.
It should be noted that the current carrying capacity of wire depends only on its size and is the same for all voltages and phases.

Is the national electricity service in Bolivia split phase or single phase?
Bolivia uses the same as electricity service standards as countries in Europe: 230 volts 50 Hz single phase alternating current. Home appliances are fitted with Europlugs Types A and C.
What are some of the benefits of a digital electricity meter?
A digital multimeter has the advantages of idiot-proofing and accuracy. The digital readout gives a single number instead of a dial pointing to several numbers on multiple scales.
What are advantages in THREE phase UPS over SINGLE phase UPS?
You need to match the UPS to the service. If it is three phase you need a three phase UPS, and vice versa for single phase. It isn't a case of being better, it is a situation where you need to match your application.
what is the cheapest electric supply cost single phase or 3 phase?
The cheapest service to construct is a single phase service. A three phase service requires more equipment and materials to complete a service.

What is the advantages and disadvantages of single phase and three phase?
Single phase inherently requires less equipment (it's cheaper). Three phase motors are more efficient than single phase.
What are the advantages of using single phase electricity?
Simple hookups to devices you wish to power (2 wires and ground). Most household common devices use single phase.

To what can the energy content of a hurricane be compared?
The amount of energy released by a single hurricane is enough to be able to compare to the amount of electricity that the United States uses in six months.
Is electricity the same as energy?
Electricity is an energy, But energy is a category and not a single entity.
