AI Thread Summary
Connecting two computer power supplies in series to increase voltage is not feasible, as each power supply has one side returned to ground. This common ground connection prevents the supplies from being combined in a series configuration like batteries. Attempting to do so would result in short-circuiting the power supplies. Therefore, it is essential to understand the limitations of power supplies when considering voltage increases. Ultimately, using power supplies in series is not a viable option.

is it possible to connect two computer power supplies together in series to increase the voltage like with batteries or does that not work with power supplies?

No, that would not work.

This is because each of the voltages you can get out of such a power supply has one side returned to ground.

So, on the two power supplies, all these ground points are joined together and you can't put them in series.

Thread '3-terminal device external modeling'

Very basic question. Consider a 3-terminal device with terminals say A,B,C. Kirchhoff Current Law (KCL) and Kirchhoff Voltage Law (KVL) establish two relationships between the 3 currents entering the terminals and the 3 terminal's voltage pairs respectively. So we have 2 equations in 6 unknowns. To proceed further we need two more (independent) equations in order to solve the circuit the 3-terminal device is connected to (basically one treats such a device as an unbalanced two-port...

Thread 'Two capacitors, etc.'

suppose you have two capacitors with a 0.1 Farad value and 12 VDC rating. label these as A and B. label the terminals of each as 1 and 2. you also have a voltmeter with a 40 volt linear range for DC. you also have a 9 volt DC power supply fed by mains. you charge each capacitor to 9 volts with terminal 1 being - (negative) and terminal 2 being + (positive). you connect the voltmeter to terminal A2 and to terminal B1. does it read any voltage? can - of one capacitor discharge + of the...
