Mathematical approch to measuring current voltage and resistance of mixed series and parallel


Posted on Feb 6, 2014

There is one important low-impedance node in the whole circuit. That`s the frame and the cross in the middle. Let`s call that 0v. The top voltage source is connected to the middle via that 1k resistor, that means the lower voltage source has priority. the two resistors in the top half form a potential divider between 0v and 0v, so you might think

of the top voltage source as sitting at about 0v too. However, since it`s generating a voltage, then the top side will be at 5v, and the bottom side at -5v.
