Extract of sample "Electricity and Electronic Experiments"

The paper “Justifying Ohm’s Law" is a worthy example of a lab report on physics. Electric and electronic experiments have to attend laboratory experiments in order to equip themselves with practical knowledge in electrical and electronic concepts. Experiments are either done individually or groups. There is an experiment data sheet that is useful in presenting laboratory data. There are systematic ways of presenting the laboratory. The data have to be consistent. Students have the mandate to obey the safety rules of the lab and undertake precautionary measures while performing laboratory experiments (Herman, 2009).

The laboratory is useful in measuring a number of electrical quantities that confirm particular theories. For instance, Ohms law states that resistance describes the relationship between voltage and current. There are factors that can be varied to carry out the experiments. The first is to determine the objective of an experiment. An experiment that aims at justifying Ohm’s law requires instruments and equipment that relate to current and voltage (Herman, 2009). Assessing the objective of experiments helps to set up the appropriate design structure.

Some of the important equations are R = k l/A An experiment can be designed to prove the above representation of electrical factors. Varying one of the factors would result in a variation of the others (Herman, 2009). Students can represent the data in a number of ways that include tables and graphs. Second, it involves the collection of necessary instruments depending on the objective of the experiment. An experiment designed to justify if a material obeys Ohm’s law requires instruments that measure voltage and current.

There should also be an external instrument that is able to vary the factors (Herman, 2009). In order to measure the behavior of a material in relation to current and voltage, a resistor is used to vary current and the corresponding voltage is measured. The table below can be used to record the activity.  Table of variation of voltage (V) and Current (I) The data can be used to plot a graph of current against voltage. The two factors can be used to calculate electrical parameters of the material such as resistivity, conductance, and resistance.

In the actual sense, according to Ohm’s law, resistance is directly proportional to voltage but inversely proportional to current. Otherwise, there are cases when a material cannot obey the law. Such substances are called non-ohmic materials (Herman, 2009). The student records voltage and its corresponding reading of the current. The current is measured by an ammeter while voltage is measured by a voltmeter. Conditions of the system are varied by a rheostat. The rheostat functions by varying the resistance of the material.

There are several instruments in an electrical and electronics laboratory. An oscilloscope is another example of the instruments. The instrument can measure a variety of factors.The most important final part of laboratory experiments is writing reports (Herman, 2009). Reports involve a critical overview and analysis of results. The results are used to make a comparison with theoretical data as well as previous studies in order to draw a conclusion. The final conclusion should be in agreement with previous studies or should e confirmed against them.
