Question 10 of 10



  1. Greg G says:

    #10 is a bit misleading. Yes it makes no difference but the question asked what’s the best way…I’d rather have the 12 gauge first in case I unplug the 16 gauge for a power tool that requires higher amps.

  2. Daniel R says:

    If you have two 10w bulbs un series wont they draw half the amount of wattage each bejng 5w, still making total power consumed by the circuit 10w?
    I got 9/10 except for this one…

    1. Bryan Orr says:

      No, both TOGETHER will draw half so each would be 1.25W when in series.

      1. Kevin Miles says:

        Number 6 question is wrong in a series circuit the wattage would increase. Series circuits amperage stays the same voltage adds so if you have 2 10w bulbs connected to 120v supply then the bulbs would produce 0.1666 amps each a single bulb would be 0.0833 amps. the wattage would be 10w for a single bulb or 20w for two bulbs. a light bulb is a fixed resistance it will not reduce in resistance in a series circuit.

        1. Bryan Orr says:

          Hello Kevin. It isn’t wrong, it’s just deceiving because while bulb is marked with a wattage is is actually just a fixed resistor.

        2. Bryan Orr says:

          Ohms law shows us that as resistance increases amperage (and thus wattage) decrease

    Bryan Orr, you’re my hero.

    But seriously, I’ve listened to all your podcasts and I am a strong supporter. I am working on an electrical trainer for our new techs right now with basic circuits, and am also trying to put together a curriculum for a training program for the company. Glad to see like minds out there!

      I’ve never been a hero before… it feels… weird 🙂

      Thanks for the support man, feel free to use anything we have on the site.
