  • This physics video tutorial explains how to solve any resistors in series and parallel combination circuit problems. The first thing you need to do is calculate the equivalent resistance of the circuit which you can use to calculate the current flowing from the battery based on ohm's law. Using the current and the voltage drops across each resistor, you can calculate the electric potential at every point in the circuit which will allow you to calculate the current flowing through any resistor. This technique is useful if there's not multiple batteries in different loops of the equation. Keep in mind, the current flowing in two resistors that are in series with each other is the same. The voltage is the same across resistors connected in parallel. This video contains plenty of examples and practice problems including a current division formula for resistors connected in parallel.

    • @MrDoneboy
      @MrDoneboy Před 4 lety +4

      Absolutely NO redraws are necessary!. Find total resistance from right to left, back to the source voltage. Then figure the total current by Ohms law. Now, going from left to right...figure your voltage drops across R1 and R6. Then subtract those voltages from the source voltage. Divide the 15 volts by R2 resistance to get 1.5 amps, which is half of the total current. The other 1.5 amps goes thru the rest of the circuit, or just divide the 15 volts by the total resistance of the three resistors in the far right part of the circuit. Bingo, problem solved people!

  • @successthruknowledge
    @successthruknowledge Před 4 měsíci

    You do such a great job explaining multiple ways to solve the same problem! In earlier lectures you showed how to do it by summing the resistors in series on right side and then solving the parallel resistors and now you explained the alternate way to solve to find the current through the middle resistor by using the potential difference between two voltage points on either side of the middle resistor and solving for the current through the middle resistor and then subtracting that current to find the remaining current flowing through the resistors in series on the right side of the circuit! Just what I needed explained clearly!

    In physics class, to combine parallel repressors, we have been using the formula 1/Rt =1/R1 +1/R2, but that doesn't seem to be in your video. I'm still kind of struggling to understand circuits as a whole, and it would be very helpful to me if you could explain that rule/ its relevancy to circuits. The right hand rule also has been confusing me as well.
    I love your videos, they've helped me loads in AP Chem and in physics. I'm really glad that there are people out there who make videos to help others, rather than click-baited videos.

    I've recently discovered your series. I did so because I have an opportunity to test for a position in an Aerospace company as an Electronic Service Technician. This position will be responsible for diagnosing electronic systems involved in industrial controls. My degree in Electronics is 46 years old and although I have been involved in diagnosing and repairing complex electronic systems in Automotive, I feel out of my element moving into industrial controls. I have some familiarity with their systems and PLC controls due to my experience with the same company as a CNC machinist on purpose built CNC equipment. Having said all this, I am having difficulty in sorting out an order of lectures in which to study your content. Is there some kind of indexing system so I can know what lectures to study in what order? Thanks

    To compute 2 resistor in parallel with different value just multiply the Numerator then add the Denominator and Devide the value that you get in 15:31 minutes 12 * 4 = 48 (Numerator) then 12 + 4 = 16 therefore 48/16 = 3ohms
