Power source

[allaliasalreadytaken]

Hello everyone,I made a circuit on Multisim and for the power I used Vcc = 5 V and ground.When I replace the power source with a 5 V battery and replace Vcc with the + terminal and replace ground with - terminal,my circuit won't work why? What is the difference between Vcc and a DC power source?

Hi!
You replace it with the + and - terminal of what? Can you give us a screenshot?

Hello, sorry for late reply -  I solved the problem, we need to specify ground in simulation as there may be negative voltages as well in the circuit .
