Electricity (Current Electricity (Parallel (Resistance (Resistance becomes…

- - - - Current (I) through light bulb
      - Equation: V=IR
      - Voltage (V) across light bulb
    - - Rt=R1 + R2 + R3...
  - - - Resistance becomes 1/R
        
        Rt=1/R + 1/R + 1/R
    - - Voltage is always the same across all components
    - - Current splits off when comes in contact with a junction and total current is divided
        
        Current is different for every component because they have different resistances.
  - - - P=VI
- - - - 3) Outside lines are curved showing field strength weakens outside the plate.
      - 2) For maximum grade:
        
        Ruler used
        
        Lines are parallel
        
        equally spaced
      - 1) The plate that is connected to the positive terminal of the battery becomes positively charged and the one connected to negative terminal becomes negatively charged.
    - - E=V/d
        
        V=voltage across the plates
        
        Distance between plates
        
        Unit of E= Volt/m
    - - The size of the electrostatic force experienced by a charge is given by:
        
        F=Eq
        
        E= electric field strength between the plates
        
        q=charge
        
        F=force
    - - Positive charge moves against electric field
      - Negative charge moves against the electric field
      - The minus sign already indicates the direction of the charge is in the opposite direction so DO NOT say to the left if you add a negative symbol.
    - - To place an electron in between the plates, work must be done. This is similar to raising an object to a certain height above the ground. The work done in moving a charge in an electric field will be stored as electric potential energy. (similar to gravitational potential energy)
        
        Electric Potential=Work done energy.
        
        Ep=F times d
        
        Ep=Eq times d
        
        Ep= change in Voltage times colombs
        
        Ep=V times q
      - The rest position is the opposite is the opposite charge plate.
    - - Note this can only happen with a variable power supply
- - - - F=BIL
        
        Fingers are the direction of the magnetic field
        
        Thumb is the direction of the current
        
        The palm of hand is the direction of the force
      - F=BqV
        
        When a charge (q) moves with a velocity (v) into a region of magnetic field (B), it will experience a force due to the interaction of the electric and magnetic fields.
