Hey, welcome to the Mattcave.   **__Summary of Mr. Coulomb__** Chapter 1: - Matter made of atoms - No Charge - Charge measured in Coulombs (C) == 6.242e18 elemtentary charges - Same charges repel - Different charges attract - Insulators cause more Static Electricity Chapter 2: - - k=9e9 q's= Charges r= distance in metres - Point charges only -  - Electric Fields Chapter 3: - Batteries = Non static charge - - I = Current (Amps), q = Charge (Coulombs), t= Time (Seconds) - Protons go from + to - - DC - Direct Current (One Direction) - AC - Alternating Current (Alternates Direction) Chapter 4: - R=V/I - R = Resistance (Ohms, V = Voltage (Volts), I = Current (Amps) - Ohmic = Linear resistance increase - Non-Ohmic = Non-Linear - R = (pL)/A - p = Resistivity of material, L = length (m) Chapter 5: - Energy = Joules - E = vIt (Energy Equation) - P = VI - P = Power (Watts) - 1 kWh = 3.6gj   It is a bit messy, but it has a lot of detail--1221008277 it is really good and informful
 * __I Love how organsed this is i really find it read to use 1221008013

The electrodes at the end of the stun gun then recieve this amplified voltage, and when a conductor joins then together, the amplified voltage then passes through it, from electrode to electrode. <span style="COLOR: rgb(65,106,134); FONT-FAMILY: 'Lucida Console',Monaco,monospace; BACKGROUND-COLOR: rgb(0,0,0)"><span style="COLOR: rgb(38,82,115); BACKGROUND-COLOR: rgb(255,255,255)"><span style="COLOR: rgb(51,77,113); FONT-FAMILY: 'Lucida Console',Monaco,monospace"> Lightning: Lightning doesn't always strike from cloud-to-ground, it can go either way. Ground-to-cloud lightning happens when a negatively charged leader (which is invisible) reaches down towards the ground, causing a positive discharge from the earth, which is what creates the actual lightning strike. Survioving Lightning: Stay inside if possible, stay away from metal/electrical objects, wear rubber soled shoes and/or stand on a plastic or rubber surface. Curl into a ball with your head tucked in to avoid getting struck on any major organs.

Sweaty Electricity: Being sweaty means there is water on your body, and water conducts electricity, so you are more conductive if you are sweaty, therefore more danger of shock.

Exploding Trees: Trees can explode when struck by lightning because the sap just under the bark can heat up really quickly, causing an explosion.

AC-DC: AC = alternating current, current randomly swaps direction. DC = Direct current, electrons always flow in one direction.

Power lines: Power lines use High Voltage-Low Current because using lower current means there is less power loss through resistance. P(loss)=IsqxR

Place comments on my page here, Louk... As you wish, caretaker of the Mattcave. Good to see you've done the homework. Perhaps next time you could cite your sources i.e. put a link to where you got all your info from. Now, I think you need to do more on Mr Coloumb - you only have Chapter 1 done! Good job 1219882940
