A small disadvantage of delivering electrical current as alternating current (AC) is that any electrical equipment which needs direct current (DC) cannot run on it. In order to run such equipment, the AC has to be rectified to convert it to DC.
Alternating current (AC) has sinusoidally varying voltages and currents which flow backwards and forwards, unlike direct current (DC), which does not change its direction of flow. Because of this, Transformers can easily be used to convert AC voltages and currents, meaning that AC can be very efficiently transported over long distances and then distributed in local communities. AC is more commonly used than DC for electrical power distribution simply because transformers do not work on DC.
electricity! Because it is a non-metal

Electricity is not bad, it is good! Like any useful tool, it can be misused, and can hurt you, but used properly, electricity makes many things possible, such as WikiAnswers!
rubber
zinc is a good conductor of electricity
No hydroelectricity is not bad for human.
It is bad to have electricity on all the time because it makes your energy bill high alsobad 4 environment
of course,we know how lemons conducts electricity in the same way we can also conduct electricity by orange
insulator
it is a bad thing for pakistan
there are no bad uses of hydro electricity and cant be
All metals are pretty good conductors of electricity.
