  1. Why is the formula for the equivalent resistance of parallel …

    Feb 13, 2025 · When you connect resistors in parallel, the resulting resistance will be less than the lowest-value resistor. Each resistor you add offers an additional path for current to flow.

  2. current - Why does placing resistors in parallel decrease the ...

    A parallel circuit decreases the resistance compared to a circuit where there are no parallel branches. Say you had 2 100 ohm resistors in parallel. Then you add a third 100 ohm resistor …

  3. Why is the resistance of parallel circuits lower than either of the ...

    Apr 5, 2021 · Wouldn't it be impossible for anything to move through with less than 100Ω resistance? My understand is that the electrons want to get from positive end of the voltage …

  4. Resistors in Parallel - Electrical Engineering Stack Exchange

    Mar 12, 2012 · 3 I understand that when you put Resistors in parallel the resistance decreases, my question is why does this actually happen? What causes the Resistance to decrease? …

  5. current - Why does LED dim when adding second LED in parallel …

    Jan 16, 2020 · 0 If I have a led hooked up to a 12v DC supply with a single resistor it runs nicely as you would expect. If I add a second LED in parallel the brightness drops, slightly, the …

  6. How to combine two resistors with a voltage source

    May 29, 2020 · Sometimes, when you're still new to all this, it just isn't clear if two circuit elements are parallel (or series) connected. If you're not sure, there's an easy 'trick' to test whether or …

  7. Reasons to use combinations of resistors (parallel or in series ...

    Jan 25, 2024 · 16 I teach physics at high school level, and one of the topics I cover involves instructing students on how to calculate the total resistance of two resistors, whether in …

  8. A battery with zero internal resistance connected to identical ...

    Aug 26, 2022 · How is it possible that the current in each branch of a set of identical resistors in parallel would change when adding one more parallel resistor? I know that since the battery …

  9. Why does adding a resistance in parallel decreases the circuit total ...

    May 26, 2022 · Why does adding a resistance in parallel decreases the circuit total resistance? Before you close the questions a duplicate, please read further: I know the classic explanation …

  10. impedance matching - Can I add a resistors to add speakers ...

    Mar 28, 2024 · The speaker connectors on the amp are marked 4 Ohms. I have four more 4 Ohm speakers that I would like to add in parallel, but doing so would lower the impedance of each …
