Basic Rules Of Electricity

Avoid contact with energized electrical circuits.

Basic rules of electricity. If you are working on electrical circuits or with electrical tools and equipment you need to use following golden safety rules. Safety must not be compromised and some ground rules need to be followed first. The fundamental laws of electricity a strong foundation for any electrical worker is built on a thorough knowledge of the laws that govern the operation of electricity. When an electric circuit flows through a conductor a magnetic field or flux develops around the conductor.

This law basically states that current into a node will equal the current out of the node. Looking at the node. The current entering any passive circuit equals the current leaving it regardless of the component configuration. Introduction to circuits and ohm s law.

This electric current takes the form of free electrons that transfer from one atom to the next. Namely electric charge electric current and electric circuit. Please don t make fun of this rule if you already know this and you probably already know if you are reading these lines and remember that if something bad occurs you. Electric charge refers to a fundamental property of matter that even physicists don t totally understand.

Let s start with three very basic concepts of electricity. Rule 1 electricity will always want to flow from a higher voltage to a lower voltage. Never touch or try repairing any electrical equipment or circuits with wet hands. In other words the net current in a node is zero or 0 i in i out.

Rule 2 electricity always has work that needs to be done. But what is electricity really. Google classroom facebook twitter. We ve organized these principles into three basic rules.

Thus the more free electrons a material has the better it conducts. Ohm s law and circuits with resistors. Rule 3 electricity always needs a path to travel. 21 golden safety rules.

Avoid water at all times when working with electricity. In electronics and electrical technology a coil is usually known as an inductor. Build an intuitive understanding of current and voltage and power. A voltage of 1v across a resistance of 1 ohm will cause a current flow of 1 amp and the resistor will dissipate 1 watt all as heat.

Written by willy mcallister. This current varying in parallel circuits brought about kirchoff s next big law in basic electrical engineering kirchoff s current law kcl. The basic principles of electricity. The highest flux density occurs when the conductor is formed into a coil having many turns.

The basic guidelines regarding the safe handling of electricity documented below will help you while working with electricity. Suffice it to say that two of the tiny particles that make up atoms protons and electrons are the bearers of electric charge. Electricity simply put is the flow of electric current along a conductor. Basic electricity is described in many ways.
