EMG - Coggle Diagram

- - - - for uniform, lines are straight, parallel and equally spaced
      - E = force/unit charge experienced by positive test charge
      - !gotta review derivation
    - - conventional flow = + ---> -, electron is opposite
    - - v=(w/e)/q
      - (work done or energy)/charge
  - - - parallel vs series resistors
        
        parallel = 1/r1 + 1/r2...
        
        series = r1+r2...
      - E = sum of voltage
      - current supplied = I1 + I2 ...
    - - Conservation of charge
        
        sum of I in = sum of I out
      - Loop rule
        
        sum of voltage rises = sum of voltage drops
    - - r=v/i
    - - current flowing into conductor is proportional to potential difference
      - v = ir
      - not always obeyed
    - - proportional to length and inverse proportional to wire cross section
      - R= pL/A
    - - learn the derivation
      - E/Pt
      - basically energy lost to heat and stuff
  - - - battery = at least 2 cells
    - - resistance of the material
    - - potential difference at terminals < emf (cuz internal resistance)
    - - E = V + Ir
      - E = I(R + r)
        
        lil r = internal resistance
      - energy/unit charge supplied by source
  - - - caused by magnets or moving charges
      - perpendicular to the charge's direction
    - - magnitude of the force on a wire carrying current
      - F = IL x B
      - check the diagram & derivation for it
      - F = qBvsin(theta)
- - - - the product is called a daughter nucleus
