Basic Concepts of Electricity

An electric circuit is defined as a closed path where current flows. It is basically composed of a source, a conductor, a switch and a load. The circuit is actually complete without a switch, but it has been considered as a basic component because almost all electric circuits nowadays include a switch.

The source, as the name applies, is the one that provides power to the circuit. It can be a form of a 110-volt power line or just a single dry cell. The conductor of an electric circuit is a pair of metals, usually wires, that completes the path of current from the source to the load and vice versa. Meanwhile, the load is the one being powered by electricity. The usual household appliances that are powered are light bulbs, TV, radio and electric fan.

There are two main types of an electric circuit. The first one is the series circuit where loads are connected end to end. The advantage of this type of circuit is the ease of turning it on and off. In series circuits, disconnecting one of the loads will turn off the whole circuit. However, this type of circuit is not applicable in many systems. Most of the circuits today require individual switching and thus, the parallel circuit type is used. Aside from individual switching, the parallel circuit is also used because the voltage drops for each load are equal and the same with the source. For a comparison of circuits with a 12-volt source, four light bulbs connected in series will have three volts on each bulb while four light bulbs connected in parallel will each have twelve volts voltage drop. In practical applications, combination of the two types of circuit is also common.

Electricians in Minneapolis are required to master these basic concepts in electric circuit. Dealing with electricity is not a simple task. It involves proper calculations and in-depth understanding of the principles of electricity.

Safety is another important thing to be considered when dealing with electricity. The electricians Minneapolis has are trained to have the necessary safety skills in doing tasks regarding electricity.

Lastly, electricity is a complex study that is a part of physics. Therefore, the electricians in Minneapolis must perform according to the appropriate scientific attitudes as well as the scientific methods.
