### Lab Explained: Ohm’s Law Lab

Research question: How will increasing the voltage (v) to 5v, 10v, 20v, 35v, and then 50v affect the amount of current (Amps) measured by an ammeter, keeping the resistance (ohms) at 12 ohms and the wire length of 10cm constant, in a series circuit to prove ohms law? Background information on Ohm’s law: Ohms law…

### Lab Report Explained: Length and Electrical Resistance of a Wire

INTRODUCTION AND BACKGROUND THEORY When electrons travel through wires or other external circuits, they travel in a zigzag pattern that results in a collision between the electrons and the ions in the conductor, and this is known as resistance. The resistance of a wire causes difficulty for the flow of the electrical current of a…

### Martin Luther King, Jr.: Nonviolent Resistance

In Martin Luther King, Jr.¹s selection, Nonviolent Resistance which first appeared in 1958 as a part of his book Stride Towards Freedom, he describes the processes people follow as they confront their situation. There are three ways he explained how oppressed people can deal with their situation. The different processes that are opened to the…

### Capacitance & Resistance

Capacitor: two conducting plates charged with equal amount of charge of opposite signs, with insulator in between (we assume a vacuum unless said otherwise) Three quantities characterize a capacitor: 1) surface charge density 2) capacitance 3) dielectric constant Capacitance (q= C x ∆V) Unit: Farad (F) The potential difference across a parallel plate capacitor is…

### Slavery in Ancient Greece

Ancient writers were aristocrats, they didn’t know what it was like to be a slave, to be a Sometimes masters would breed slaves If someone who was freed, had children with another non-citizen, the children were free but had limited rights, not citizens Sources – worthless because masters always shown the slave as goofing off…
