Feb 12, 2017 · Specifically, I am confused on how to find the voltage of a parallel circuit if the resistor is in front of it. Do I use the original voltage source, or the Voltage of the parallel circuit?

Dec 1, 2018 · A 60W bulb doesn't "know" it's supposed to pull 60W. It has a (fairly) constant resistance (once it has warmed up) which determines how much current it will draw when …

Jul 22, 2021 · The technique is absurdly simple. You take the circuit and replace each battery but one with a wire, or with a resistor equal to their internal resistance if they have an internal …

Don't know why they test us with such strange diagrams of circuits, when all it is a simple series-parallel combination. $\endgroup$ – udiboy1209 Commented Aug 21, 2013 at 19:02

May 8, 2022 · $\begingroup$ I would define three current loops, and then write and solve three voltage loop equations. $\endgroup$ – R.W. Bird Commented May 8, 2022 at 18:09

Mar 31, 2019 · Substituting in the initial values for the current, $0.2A$, and for the voltage, $10V$, we calculate the maximum current to be $0.44A$. Like I said above, that seems wrong to me …

Mar 19, 2021 · Let's say that I have a circuit consisting of a power supply of $220V$ and $2$ bulbs of power-voltage rating $40W-220V$ and $60W-220V$ in series. How would I calculate …

But, there are no ideal voltage sources, i.e., all real voltage sources have some maximum current delivered into a short circuit. This is modelled by placing a resistor in series with an ideal …

Nov 12, 2020 · You can solve this circuit fairly easily with common differential equation methods. I prefer Laplace Transform methods and will show you how to solve this circuit below with that …
