Automatic Fuse Circuit
To restrict / security, electric current is usually used fuse or patron is dissolved when going short will drop out and must be replaced with a new one. Then, in order not to drop out of each new change means that more money out to buy, then there fuse automatically work with the reset button. So there are problems with each short, fuse will automatic decided flow then to return it does not need to buy a new (if not broken) just press the reset the equipment will live again. Circuit Diagram Automatic Fuse Circuit is one of the simplest electronic fuse circuit one can make. The circuit uses only one transistor, one SCR, one push button switch and two resistors. The value of R1 can be obtained from the equation; [Imax] X [R1] = 0.7V. R2 can be obtained from the equation; R2 = [Vs] X [1K Ohms]. Wattage rating of R1 can be obtained from the equation; W = [Imax] X [Imax] X [R1]. For this circuit to work the current consumption of the load must be greater than the holding curr...
