The discussion centers on the consequences of connecting alternating current (A.C.) and direct current (D.C.) voltage sources in parallel. It is established that doing so leads to a conflict between the two sources, resulting in potentially infinite currents if both are ideal sources. This scenario can cause catastrophic failures in one or both sources or the connecting wires. The correct answer to the posed question is that such a configuration is fundamentally flawed due to the inherent differences in voltage behavior between A.C. and D.C.
PREREQUISITESElectrical engineers, students studying circuit theory, and anyone interested in understanding the risks of connecting A.C. and D.C. sources in parallel.
Both voltage sources will insist on forcing the result to be equal to their own values. The resulting "struggle" between them will make them want to produce very large currents indeed; if they are ideal sources the currents would be infinite!. One or both of the sources or the connecting wires between them must fail (zzzzZZT! BANG!). Not so good950315 said:Homework Statement
So my question is, why isn't D a correct answer?
And also, what will happen to the voltage and ampere, if I connect a A.C. and D.C. parallel?
