@a1ba@suya.place @koakuma@uwu.social Yeah, usually inductors. But occasionally also ceramic capacitors (both class-2 ceramic caps and buzzers are piezoelectric). Even more rarely, the circuit board itself. A current pulse around over 100 amps can create Lorenz force that mechanically bends the circuit board when it fires. |
