Series parallel circuit elements lab report

Kirchhoff's Rules Electronic devices contain circuits made up of many elements. Current "flows" through the elements, and when a voltage source is in the circuit, there will be voltage differences across these elements. For a direct-current circuit meaning that the current does not change with timethe voltage and current at any position in the circuit can be calculated using Kirchhoff's rules. Within a circuit, there are points we will call "junctions".

Introduction Historically, the study of electricity began with electrostatics, the study of stationary charges. Static devices were used in the 's by Franklin, Coulomb, and others. The important discoveries leading to the present widespread use of electricity came at the start of the 19th century when the battery was invented by Volta, electric currents and their effects were studied by Ampere and Oersted, and dynamic effects of changing electric and magnetic fields were investigated by Faraday, Henry, Maxwell, and others.

The practical applications of electricity to human life followed with the invention in the late 's of light bulbs, motors, telephones, etc. Studying the physics behind these discoveries will occupy most of this course. The study of electric circuits, current flow, and its measurement is the subject of this laboratory exercise.

Traditionally, electric charge is introduced as the primary electrical quantity, measured in coulombs in the SI system of units. However, in actual practice the electrical unit which is defined and measured at the National Institute of Standards and Technology is the ampere, the unit of electrical current.

Many common electrical measurement instruments are based on electrical current. This first lab exercise seeks to give you some rudimentary understanding of these instruments and to demonstrate their correct and intelligent use.

The course lectures may not yet have presented fully the principles behind the operation of these instruments, but do not despair most of the circuitry inside modern instrumentation cannot be entirely explained during any introductory course!

Athough you may not understand the details of what is inside the meter, you do need to learn how to connect and use the meter properly and comprehend the meaning of the readings. After all, most people drive safely without a detailed understanding of an internal combustion engine.

Failure to use the laboratory instruments appropriately may break them irreparably, incurring frustration on you and your laboratory instructor from waste of time and resources. Safety A complete circuit is needed before electric current will flow, a convenient feature for working safely with laboratory circuitry.

If you do not plug in the power supply or turn it on, you can work on most circuits without fear of being shocked. Capacitors in high voltage circuits, such as in video monitors, can remain charged for long times after the power is turned off.

Always discharge capacitors before handling! Therefore, when setting up a circuit, turning on the power should be the last step, and turning off the power is the first step before touching or changing any section of the circuit.

Another safety guideline is to always work with one hand behind your back or safely out of the way; i. Damaging current flow through your upper chest may result if your body serves to complete a circuit between your right and left hands.May 01,  · Evaluate simple series and parallel circuits to predict changes to voltage, current, or resistance when simple changes are made to a circuit.

Technology/Engineering Progression Grades The use of electrical circuits and electricity is critical to most technological systems in society.

Learning Goals

A third type of circuit involves the dual use of series and parallel connections in a circuit; such circuits are referred to as compound circuits or combination circuits. The circuit depicted at the right is an example of the use of both series and parallel connections within the same circuit.

Series Circuits: A brief introduction to series circuit and series circuit analysis, including Kirchhoff’s Current Law (KCL) and Kirchhoff’s Voltage Law (KVL). Resistors in Series Resistors are in series whenever the flow of charge, or the current, must flow through components sequentially.
