Electricity, Measuring Current - Ammeter - Coggle Diagram

- - - - :
- - - - V (Volts): The electrical pressure or force pushing the charge.
      - I (Amperes): The rate of electrical flow (current).
      - R (Ohms): The opposition to that flow (resistance).
      - Greater resistance decreases the current.
      - Greater voltage increases the current.
- - - - same current in each point
    - - The voltage of the battery is the sum of all voltages.
  - - - The voltage is the same in every branch. V1 = V2 = V3 = Vn
        
        The current of the battery is the sum of all currents IT = I1 + I2+ In
      - Voltmeter is always connected in parallel .
  - - - advantage
        
        1.They are very easy to set up because they only use one path and fewer wires.
        2.Does not overload the power supply.
        3.Components can operate
        on different voltages.
      - disadvantage
        
        1.If a single light bulb blows out or one component breaks, the entire circuit is broken, and everything stops working.
        2.Current flows through all devices
        must be equal
        3.If have many bulbs,
        the brightness of the light reduces.
    - - disadvantage
        
        1.All components must operate
        on the same voltage.
        2.All components must operate
        on the same voltage.
      - advantage
        
        1.The electricity has many paths, so if one path is broken, the others are unaffected.
        2.Each device can be
        controlled separately
        3.Each device can use different
        current as needed.
- - - - 2.If there are 4 bands: Read the first two colors as the first and second digits.
        
        3.The next band is the "multiplier." This tells you how many zeros to add, or the factor to multiply by.
        
        4.Check the Tolerance: The final band represents the tolerance (e.g., plus/minus 5%)
- - - - When you only have two resistors in parallel, you can use a simpler "product-over-sum"
