There were many resistances from slaves‚ violent and non-violent‚ during the period of slavery in the BWI. Violent resistance was in the form of revolts and rebellions and non-violent resistance included actions such as suicide‚ poisoning‚ avoiding work and maroonage. However‚ there were three violent resistances which stood out. These three were Bussa Rebellion in Barbados (Easter 1816)‚ Demerara Revolt in Guyana (August 1823) and the Sam Sharp Rebellion in Jamaica (December 1831). These rebellious

circuit and measured some circuit elements such as voltage‚ resistance‚ current and power. From the obtained data we can see the relationship of the resistance and current. The Ohm’s Law was very apparent with the data gathered. In Ohm’s Law we know that when voltage and other factors are held constant‚ the current ( I ) is inversely proportional with resistance ( R ). Thus‚ it was projected in the values we got that as we increase the resistance‚ the current decreases and vice versa. Looking at

Study about Ohm’s Law: • To verify Ohm’s Law by calculating voltage‚ current and resistance based on different views of Ohm’s law as well as measuring those values to compare the theoretical results with the actual results. • To verify the relationships of R-I‚ V-I and R-V given ohm’s law by increasing one parameter while holding the other parameter constant‚ then measuring and calculating equivalent results of the third parameter. What is Ohm’s Law: Ohm’s Law is made from 3 mathematical equations

relationship between the variables of Ohm’s law and how they are part of an operation of an electric circuit. Introduction: This experiment was done in two parts. The first part consisted of understanding how to determine the current‚ voltage and resistance as part of Ohm’s law. The second part consisted of how to use the variables in an electrical current. Knowing how the variables are used in calculations and electrical currents is important in determining the value of the resistor and how it affects

While Duncombe talks extensively about the various types and stages of cultural resistance‚ the overall idea is to rebel against an overarching societal system that is oppressive in some manner. This resistance can be presented through arts and media‚ action‚ or personal attitude. The author believes that any movement of this nature against the norm can create new school of thought on one end and a full-blown revolution on the other. Duncombe begins his piece by stating his observations of the rave

current and resistance are closely related to one another. The outcome from this lab is to be able to differentiate when to use ohmmeter and voltmeter for the individual circuit. II. Theory Ohm’s Law states that the electric current through a material is directly proportional to the voltage across a piece of material (such as wire) while the resistance is held constant. mathematical equation provides more detailed understanding of the law and is stated as : (or) where‚ R= resistance in ohms (Ω)
