Address Latch Enable:-
Address Latch was Intel's way of limiting the number of pins on their early microprocessors, to limit the production cost.
Sadly this "feature" remained in Intel processor architecture for several generations, despite the fact that production cost was no longer an issue.
What it does: On the early processors there was an 8 bit bus acting both as an address and a data bus (to save pins). Then there was the ALE (Address Latch Enable) pin, that determined if the bus should act as data or address bus. This of course decreased the efficiency of the processor, because you had to switch back and forth between the two states, according to which bus was needed.
Latching Current is the minimum current needed on the gate to fire or trigger an SCR.
The doorknob may not be latching properly due to misalignment, wear and tear, or a loose screw.
we know that ratio of holding current to latching current in scr is 0.4.
The door handle may not be latching properly due to wear and tear, misalignment, or a faulty latch mechanism.
The door knob may not be latching properly due to misalignment, loose screws, or a worn-out latch mechanism.

The door may not be latching properly due to misalignment of the latch mechanism, a worn-out latch, or a problem with the door frame.
The door may not be latching properly due to misalignment of the latch mechanism, worn out latch components, or a loose door frame.
Latching current is the current flowing between anode to Cathode when thyristor is turned on using gate pulse. If the gate pulse is removed before the required min amount of latching current value is not reached thyristor will turn off. To keep the thyristor in on state the gate pulse duration should be so adjusted that the min latching current value is reached before it ends.
The door may have stopped latching properly due to wear and tear on the latch mechanism, misalignment of the door and frame, or a loose screw or hinge.
Your interior door may not be latching properly due to misalignment of the door and frame, loose screws or hinges, a damaged latch mechanism, or a warped door.
Your front door may not be latching properly due to misalignment of the door and frame, worn out latch or strike plate, loose screws, or debris blocking the latch mechanism.
