Electricity and Magnetism Background

I. Famous people
 
Volta
 
Gilbert
 
Faraday
 
Oersted
 
Tesla
 
Hertz
 
 
 
II. water flow related to electrical current flow
 
 
III. energy of the battery is defined by its voltage
 
How does the current change when the voltage is held constant and the resistance of the resistors in increased?
 
 
IV. Oersted - magnetic fields around wires
 
compass orientation
 
circular fields
 
forces between parallel current carrying wires
 
field inside a current-carrying coil of wire
 
 
V. Faraday and electromagnetic induction
 
current induced in a coil by changing the proximity of a magnetic field (bar magnet)
 
current induced in a coil by changing its area
 
 
induced voltage in a secondary coil by changing the currents in a primary coil
