Blown fuse indicator circuit

This is very useful circuit because most of time we all have to face lots of troubles if the fuse has blown away so this is the answer for that by using this circuit you can recognize whether fuse has blown or not because the LED indicates it.

*1N4007 for D1,D2,D3 and D4

*230V primary,12V secondary ,2A step-down transformer for T1

*2A fuse

*1000uF/25V capacitor for C1.

NOTICE

# The circuit will not work if the load is not connected.
# A highly resistive load may also impart the working of the circuit.
