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)

demonstrations‚ despite cause‚ is the debate on the amount of influence their resistance holds. Although there are many ways to fight unjust laws‚ renowned activist have advocated for a nonviolent approach to fighting injustice. However‚ nonviolent actions are a passive form of opposition that are counterproductive and offers one approach to the complex political issues that plague society. Therefore‚ peaceful resistance negatively affects a free society by creating several harmful implications that

Peaceful resistance to laws positively impacts a free society because it informs and educates the government on how Americans react to certain laws. This can be observed in many of the current events that are going on in America today and have gone on the past the past. One prime example of this is during the 1960’s Civil Rights Movement. Charismatic leaders such as Martin Luther King Jr. peacefully influenced American politics and ultimately brought about the Civil Rights Act of 1964 which disallowed

critical devices that enable wireless products. Unfortunately‚ system designers often choose antenna dimensions in an ad hoc manner. Many times the choice of antenna dimensions is driven by convenience rather than through the examination of fundamental electrical limitations of an antenna. In this presentation the fundamental limits and the trade-offs between the physical size of an antenna and its gain‚ efficiency and bandwidth are examined. Finally‚ we examine the difficulty experienced in determining the physical
