Ohms Law: One Of The Most Indispensible Laws In Physics
Physics Lab Report
Ohms Law Ω:
One of the most indispensible laws in physics that describes electrical circuits is the Ohms Law. In accordance to Ohms law, there is a relationship between current flow through the circuit and the voltage drop. The law also states that the voltage across any conductor is directly proportional to the current through it. In electrophysics the term resistance is used for proportionality. All this can be summed up in the famous equation of Ohms law which is: V=IR. Where the V is an abbreviation for Voltage, the I stands for current and the R stands for the resistance. This Law can be credited to the german physicist, Georg Ohm who was the founder of this theory in 1825 in his famous book published in 1827 in the

In physics, this device is known as resistor. Resistance is also the scientific word used for proportionality in physics. In consonance with Ohm's Law, Current increases whenever Voltage increases at a exact ratio and this ratio is known as the resistance. We confirmed this in the lab when we used different voltage measures and we found that the resistance always remained consonant. Resistors can be arranged either in series or parallel circuits. In the lab we connected the circuit both in parallel and series. Our observations from the parallel was that the total resistance was calculated as 1/Rt=1/R1+1/R2. In contrast, the total resistance we got from the series connection was basically adding up all the resistors and equation likewise it would be …show more content…
I already scrutinized how the electric circuit works. Now it is time to show you how I proved Ohm’s Law. To prove the Ohm’s Law, we conducted an experimental investigation using an adjustable power source, Ammeter, and a voltmeter. What we first did was that we adjusted the voltage to 2V and the resistance was 10Ω. This made the current 0.2A and we got the ratio between voltage and current as 10. We went further in investigating this Phenomenon by adjusting the voltage 6 times to check if the ratio stayed constant. We used 4V,6V, 9V, and 12V and the final outcome was that the ratio remained constant and thus this experimental investigation proved Ohm’s

788 Words | 4 PagesInitially, a 10kΩ resistor was used instead of 1kΩ. However the sound produced from the speaker was too soft. With guidance from the lecturer and student tutors, it was decided that 1kΩ would be used instead of a higher resistance value. The reason for this is simply because of Ohm’s Law. With the voltage set at 3V, a higher resistance will result in a lower current.

712 Words | 3 PagesV= IR seems a pretty simple law to name after someone, but the importance of Ohm 's work does not lie in this simple proportionality. What Ohm did was develop the idea of voltage as the driver of electric current. Ohm had to face a lot of opposition. This discovery was not accepted until 1841 (“A Timeline Of History Of Electricity,” n.d.).

A public law is between an individual or a group of individuals and the society; whereas private law is between an individual/s and other individual/s. A public law helps establish rules between people and their community, whilst private law establishes rules between people, hence the name private.

733 Words | 3 PagesThe United States in the early 1930s saw nearly ninety percent of its urban population with access to electricity, which allowed them more efficient uses of machines like electric stoves, coffee makers, waffle irons, hot plates, electric roasters, and Waring Blenders. At that time, it was financially difficult for private companies to supply urban areas with electricity for numerous reasons, primarily because farmers were often too poor, too widespread, and too few to actually produce a real profit from. Still, rural life without electricity was hard. Farmers had to rely on dim kerosene lanterns just to do their work, the absence of electricity in opposition to cities aided in their isolation, and the general standard of living was dangerously

In 1752 he sent a record of his analysis to the Royal Society of researchers in London and to French researchers. The outside researchers were so inspired with his work that he was chosen a kindred of the Royal Society in 1756 and granted its Copley Medal. In 1773 he was chosen one of the eight remote partners of the Royal Academy of Science in

492 Words | 2 Pages2-a. The current drawn by each shunt resistor is linearly proportional to the cell voltage. As the cell voltage increases, more current is drawn by the shunt resistor. This will decrease the voltage differences between the different cells within the battery system since higher voltage cells is further discharged by the shunt resistors. It is worth mentioning that this method can be only used for Lead-acid and Nickel based batteries because they can be brought into overcharge conditions without cell damage [4r]. Its features are simplicity, low cost but the excess energy is converted into heat losses in the shunt resistors.
