Circuit Breakers Are Safer Than Fuses. Circuit breakers are safer than fuses. The wire that burns can arc and cause fires. Assuming the circuit on the circuit break trips (and it is actually very rare this doesnt happen when needed) then you eliminate the probability of arcing causing a fire.
The principle behind a metal detector is really very simple. Proof of this is the circuit that follows, in which it proves that the construction of a metal detector can be done in the minute, with few components that we find very easily everywhere.
