Actually i don't know how to desing fuse for 20 watts cfl bulb. What i am doning , i have supply 220v to a room and the condintion is in a single room it can use a cfl bulb of 20 watts only, if a person in a room use cfl bulb more than 20 wats it should blow the fuse, acordind ti my basic knowledge i have calculate fllowing:
give,
V=220volts
P=20 wats
consider power factor for cfl=0.6
therre fore current flow throug circuit is I=20/(220*0.6)=0.1515Amps current
CAN ONE FIND 0.15 Amps fuse in market? Acyually i canot find it..
how to design this 0.15 amps fuse?
