Fuel availability generally dictates the type of standby generator selected as different types of generators use different types of fuel. For example, gasoline generators are typically used in residential or small commercial applications, while diesel generators are usually used in larger industrial and commercial applications. Propane or natural gas generators may also be used, depending on the availability of fuel sources.

Answer : C

AC can be transformed from a low voltage to a high voltage and back again with a transformer, while DC cannot. This makes it easier to distribute AC electricity over long distances and is why it is used more widely than DC electricity. A and B are also true, as wires carrying AC can be bare and don't need to be totally insulated. Wires have less resistance when carrying AC electricity, which is why it is more efficient than DC.

Answer : A

A grounded wire is connected to metal appliance cases in order to provide a safe path for electricity to flow in the event of a short circuit or other electrical problem. This helps to protect the appliance and the people using it from potential electrical shocks, and it also helps prevent fires and other accidents.
