I have been trying to test an 8Ω speaker, but I am having some difficulties. I have tried to test the circuit using multisim using the circuit below:
I used the 8Ω resistor in the place of the 8Ω speaker in the circuit. When simulating, I get about 106mA, which should be enough to power the speaker. However, when I built the circuit on a breadboard, I did not hear anything from the speaker. Should I be using an AC voltage source instead of a DC to power the circuit? Am I doing something else wrong? Can somebody help me troubleshoot this circuit please?
