- - - - A circuit that has only one path that current (electrons) flows through
        
        The electrons move along one line with no branches, through the resistors
        
        All the components in a series circuit are connected end-to-end
        
        If the switch is open, all resistors stop
        
        If one resistor breaks, the entire series is turned off
      - resistance
        
        More components = more resistance
        
        Increase resistance = decrease current
        
        If one resistor stops, the other will stop because their will be no flow of electricity coming
        
        because it hasn't reached the positive end
        
        R_total = R1 + R2 + R3
      - Current
        
        the same at all points
        
        Less current = less bright bulbs
      - voltage
        
        As voltage increases, current increases
        
        is equal to the energy supplied by the cell
        
        Vtot = V1 + V2 + V3…
        
        if we add more components, the total voltage will be split around all components
        
        if we and more cells, the current and voltage will increase (the total and in each component)
    - - A circuit that has more than one path for current (electrons) to flow
        
        If one resistor stops, the other won't stop because it's on a different branch
        
        Components can be switched on and off independently
        
        If a component in one branch stops working, the others aren't affected
        
        The amount of current isn't the same for entire circuit
      - Current
        
        current is shared between all components
        
        Each branch can carry a different amount of current
        
        The total current = to the sum of the individual branch currents
        
        Adding more components increases the total current drawn from the power source and the current increases
        
        does not decrease the current
        
        decreases the overall resistance
        
        Itot + I1 +I2 +I3...
        
        depending on its resistance
      - voltage
        
        the voltage is the same through out
        
        Vtot = V1 = V2 =V3...
        
        even if the components are different
        
        increases the voltage of each branch
      - resistance
        
        When we add a new branch in parallel, the resistance decreases
        
        When we add a new component on the same branch the resistance increases on that branch
        
        and the current from the source decreases and decreases the current in that branch only
        
        and the current from the source increases, and this new current will go to the new branch
    - - measured in amps (A)
      - Current flows from positive to negative and electron flows from negative to positive
      - the flow of electrons through a conductor (wire)
- - - - open circuits
    - - closed circuits
    - - shorter line is negative side
      - the power sources
    - - The load is a small light bulb or buzzer that lights when the circuit is turned on.
        The load is also known as a resistor.
    - - voltmeter
    - - resistor
    - - Variable resistors
        
        can change resistance
- - - - between its positive and negative terminal
      - which is the force than pushes the current up
    - - max voltage used
    - - it's also produce more heat/light
