Share 'How-To avoid sparks when connecting battery'
Description of the problem to solve:
When a high enough current switching (transition to/from an on/off state) occurs in an electrical circuit, an electrical arc will form between the two switching contact surfaces, in order to oppose (resist to) this circuit change in current.
The more inductance and/or capacitance in the circuit, the bigger the electric spark will be. Capacitors can be viewed…
