Atomic Theory
The 3 principal parts of an Atom and their charges
Proton+, Neutron 0, Electron -
Opposite Charges do this
Attract
This remains the same in Series Circuits
Amps / Current / (I)
In Parallel this always remains the same throughout the entire circuit
Volatge
number one cause of fatalities in construction
Falls
This makes up the Nucleus
Proton + Neutron
A material that can be easily magnetized
Ferromagnetic
(10) 12V Car batteries wired in Series will produce what Voltage
120V
In parallel resistance is added using this formula
The Reciprocal formula
This must be done before each use of a ladder
Inspection
An atom of an element cannot be this
Broken down into a simpler substance
A Magnetic Field is Produced when a conductor is energized. When another conductor cuts that magnetic field, a current is induced in that conductor. Transformers take advantage of this principle.
Electromagnetic (Induction)
In series voltage total with do this amongst the individual resistances
Divide
(10) Solar Panels that are .5A wired in Parallel will have a total current of
5 Amps
How many feet should an extension ladder be extended beyond the point of entry
3 feet
Electron flow
Negative to positive
A magnet that requires current
Electromagnet
Current in series with do this with more resistors added
Stay the same
When all resistor values are the same, we can use this formula to find the total resistance the quickest
Equal resistor formula
How many people die each year from misuse of ladders
Over 300
Conductors have these many valence electrons
1-3
A magnet can be demagnetized by performing these 3 actions
Using an A/C Field (insert and remove), Striking, or Heating
In Series circuits more lights will do this the Voltage at each light
Decrease
In parallel circuits more lights will do this to the circuit current
Increases
One of the most common causes of Ladder accidents
