Week One
A Taser is an electroshock weapon that uses Electro-Muscular Disruption (EMD) technology to cause neuromuscular incapacitation or NMI and strong muscle contractions through the involuntary stimulation of both the sensory nerves and the motor nerves.

Cloud-to-ground lightning is a great lightning discharge between a cumulonimbus cloud and the ground initiated by the downward-moving leader stroke.

To avoid being struck by lightning be the least direct way to the ground, non-conductive and be the shortest thing. To survive a lighning strike you will have to be treated with CPR, this will restore your breathing. That is only if you survive the initial shock (80% do).

Week Two
Magnets. A megnetic field produces the flow of electrons.

Yes, but you would have to transfer it through a very conductive medium and even then it may not reach well enough (with enough amps).

0.1A or more MAY cause death. (Assumed from wikipedia information).

Mr Couloumb
This is showing static electricity and the charges of Coulombs

1 Coulomb = 6.242 E18 1 Elementary Charge = 1.602 E-19



F is the force in Newtons (N) k is the proportionality constant q's are the two charges in coulombs (c) r is the distance between two charges (m)



E is the strength of the field F is the force (N) q is the amount of charge (c)



I is the current in amps (A) q is the amount of coulombs (C) t is the time in seconds (s)

DC is for direct current because the electrons are always moving in the same direction. AC is for alternating current where electrons move back and forth on the same spot.

Voltage can be called electromotive force or potential difference and is the amount of energy given to each coulomb of charge when they're pushed together. As an equation, it's



V is in volts C is the energy in coulombs

Resistance is the amount of volts required to make one ampere of current flow through the resistor. Resistance is measured in ohms.



There are two types of conductors, ohmic and non-ohmic. Ohmic conductors follow Ohm's law, which says that voltage across the conductor is proportional to the current going through it.



Non-ohmic conductors do not follow this law. Resistance in wires can be calculated with:



R is the resistance in ohms. p is the resistivity of the material. L is the length of the material (m) A is the cross-sectional area of the material (m squared)



E is amount of electrical energy in Joules (J) q is the amount of charge in coulombs (C) V is the potential difference or voltage (V)



Waaaaay complicated. Looks awesome --1221008118 I didn't really look at it but it has to be better than mine 1221007621 It is way better than mine, it has more detail --1221007937 this is really good--1221008175
