Understanding Diode Current Flow

Click For Summary
Diode current flow is fundamentally different from that of resistors, as diodes only allow current to pass in one direction, from the anode to the cathode. This unidirectional behavior can create confusion, especially when comparing it to resistors where current direction does not affect the calculations. In practical applications, if current appears to flow from negative to positive through a diode, it indicates reverse bias, and no current will flow. Understanding the diode's forward and reverse bias conditions is essential for solving related problems. Clarifying these concepts will help in effectively addressing diode-related homework questions.

Homework Statement




I don't quite understand how diode problems can be solved. Whereas having inverse direction of current flow (on paper) when working with resistors didn't matter, working with diodes does. In real life if current flows through diode from - to + on paper it doesn't. I really get confused with this change of direction of current... Thank you!
