What attribute of alternating current AC increases its potential for causing electricity
Release: 2021-08-12, Update: 2022-10-17, I.R. Show There are two methods of electric current. These are direct current (DC) and alternating current (AC).
In direct current, the voltage is always constant, and the electricity flows in a certain direction. In contrast, in alternating current, the voltage periodically changes from positive to negative and from negative to positive, and the direction of the
current also periodically changes accordingly. Direct current, in which electricity always flows in a constant direction, has the following merits and demerits.
Advantages
Disadvantage
In alternating current, the direction of the current is constantly changing. Therefore, when a capacitor or inductor is included in the circuit, for example, there is a delay or advance
in the current flowing to the load in relation to the voltage behavior.
On the other hand, direct current also has its disadvantages. One of them is that it is difficult to interrupt the current. Since a constant voltage is always applied to direct current, especially when the voltage is high, problems such as arcs (sparks) may occur at the moment of interruption, or there may be a risk of electric shock in the surrounding area. AC, with its cyclic positive and negative voltage, has the following advantages and disadvantages. Advantages
Disadvantages
Especially when
transmitting power over long distances, such as from a power plant to an urban area, a very high voltage of 600,000 V (volts) is used to improve transmission efficiency. This is because power loss is much greater when power is transmitted at low voltage.
Another advantage of AC is that it is easy to shut down while power is being supplied since the timing at which the voltage drops to zero comes periodically.
There are two types of AC: one-phase AC and three-phase AC. A three-phase AC is used especially for high-voltage power transmission. When it is sent to a household outlet, it is converted to one phase along with the voltage conversion.

What attribute of alternating current AC increases its potential for causing electricity induced injury?AC can cause stimulation of sweat glands and induce sweating thus lowering our body resistance which will consequently increase the shock current. The time duration of electric shock is also important. The severity of the injuries increases with the duration of time.
Which of the following types of documents is defined as statements that describe intents what is done and why it is done?Policies are statements that describe intents: what is done and why it is done. Policies are defined by the organization and go through a management review and approval process. Examples of policies include attendance at work, employee compensation, conflict of interest, and employee training.
