In this tutorial, we are going to make and understand “Passive Filter Circuits”. Filters are circuits that can pass a particular frequency band through it while rejecting the other frequencies outside the band. Filter circuits … Read more
Passive Filter Circuit
Snubbers are the circuits of energy absorption used to smooth the circuit’s inductance voltage spikes. Overvoltage and overheating of the component sometimes fail because of the overcurrent. We use fuses at proper locations for the … Read more
