    your visual teaching method is really helpful it's just a shame not enough people know about you because you could really help a lot of people

    Why does the ammeter need to have a low resistance in the circuit?

    • @PhysicsOnline
      @PhysicsOnline  8 років тому +5

      Otherwise its resistance would reduce the very flow of current it is trying to measure.

  • @hollybee5949
    @hollybee5949 6 років тому +3

    Can someone please explain why current flows form the positive to negative terminals while the electrons are repelled from the negative and move towards the positive?

    • @PhysicsOnline
      @PhysicsOnline  6 років тому +1

      Holly Ullyott Because conventional current is defined as the rate of flow of positive charge (but electrons happen to be negative)

    • @hollybee5949
      @hollybee5949 6 років тому +2

      GCSE and A Level Physics Online I heard it was because when electricity was first discovered they assumed the positive particles were moving. Is that why the definition stands?

      Holly Ullyott That’s right

    So when you talk about current are you talking about conventional current or the direction electron flow.

      Yes they will. Just check on the WJEC spec which ones in particular, there is a full list of every video on my website. Good luck.

    Sir, I would like to ask, on which exam board do you teach students in?

    • @PhysicsOnline
      @PhysicsOnline  7 років тому +2

      Ibrahim Usman Last year it was OCR Spec A, now its AQA.

  • @JaisulNaik
    @JaisulNaik 9 років тому

    Is this exam board specific? I'm doing OCR AS and I'm starting this year? Would it be suitable for the new spec (AS exams in 2016)?

    • @PhysicsOnline
      @PhysicsOnline  9 років тому +2

      +Jaisul Naik Everything is suitable for the new spec (first exam next year), have a look at my website where there are a few resources for the OCR Spec A course.

      There's no reason why this isn't suitable, just make sure you check with the course specification to find the exact content you need.
