I understand the basics of a diode, a diode allows current to flow in only one direction, but how? By blocking any opposing voltages source so that no current can flow in opposition?
And of course, a diode has its limit. If there is a voltage in opposition that is higher to what the diode can handle it allows current to flow in opposition. What about the current that is allowed to flow through the diode is it reduced? For example: Current is supplied by a power supply it flows through a diode in forward direction, if the current was 10A before passing the diode will it still be 10A throughout the diode? If the opposing voltage existed does it reduce that 10A?
And how can I relate the forward bias to this?
