The negative sign is equally important as a positive sign. It has significance.Because voltage is difference of potentials (Vout1 and Vout2). If Vout1 - Vout2 is a negative number, then the difference is absolute value of that negative number...
Title: Understanding Basic Electronics, 1st Ed.Hello,
I have added a picture about a simple circuit. I need to find Voltmeter reading between resistors as shown in picture.
The resistor values are:
R1 = 10
R2 = 90
R3 = 30
R4 = 170
Battery is 20 volts.
Is it possible to simplify the circuit?

In an audio amplifier repair thread, we asked the TS to measure the voltage at a certain point in the circuit.The negative sign is equally important as a positive sign. It has significance.
Don’t throw away the sign.
