    I'm a 43 years first year general physics student. I really benefit from you tutorial. I don't have physics and chemistry at matric level. I qualified to study at university due recognition of prior learning. RPL. I follow both your chemistry and physics tutorial.

      This is an inspiration for those of us met with numerous challenges that hamper us from fully pursuing our dreams, education never dies and eveything takes place for a reason.
      Thank you Mr Nwamba for sharing, your comment has not fallen on deaf ears.

  • @koenatebatso4520
    @koenatebatso4520 3 года назад +2

    1.if the closed switch is connected in series ,it means that current wont flow or more current will go through the resistor?
    2. a closed switch and ammeter have zero resistance right?

    • @MlungisiNkosi
      @MlungisiNkosi  3 года назад +3

      If a closed switch is connected in series, all the current will flow unhindered through the resistor.
      No. 2 is perfect 👌🏾😉

  • @siyandablessing6168
    @siyandablessing6168 2 года назад +3

    but uncle Mlu your 9.2.2 i really tried to understand but i think you may have changed the question by mistake seeing that you assumed that current will decrease where as the question has not said that

  • @siyandablessing6168
    @siyandablessing6168 2 года назад +4

    remember in the previous video we said if switch is open then V(ext)=Emf and if swicthed is closed then V(ext)

    This electric circuit has been quite difficult Coz I'm slow learner bt anyway the way u have solved it i understand it bt what will happen if they have Given u 3parallel resistor then maybe R3? They haven't given us,how can i calculate it??

    • @MlungisiNkosi
      @MlungisiNkosi  2 года назад +1

      I don’t believe that you’re a slow learner. Look at you now… You under circuits.
      For three resistors, you still use the same formula 1/R// = 1/R1 +1/R2+ 1/R3

  • @phenyomthenjane2328
    @phenyomthenjane2328 3 года назад +3

    Hi hi am abit confused… with the explanation before the first test… I stand to be corrected i could have missed something. I dont want to quote but what i picked up is that … you had a circuit as an example and placed a voltmeter and said in parallel the current will flow where theres less resistance. Which concludes a short circuit. (Closed switch)
    So relating to question 9.2.1 isn’t the A equal to 0.27A…. (I left the 15ohm resistor out thinking it creates a short circuit)

    • @MlungisiNkosi
      @MlungisiNkosi  3 года назад +1

      Hello Phenyo, the statement says "more current goes where there is less resistance"... Don't confuse that with "all current goes where there is less resistance". There is still current flowing in both resistors.
      The only time you have a short circuit is when you put a device with ZERO resistance across a resistor like a wire or a closed switch or an ammeter.
      I hope that makes sense
