When the switch opens at ~100 msec, the current decays to zero in about 25 msec and the voltage spikes to about -60V. If the suppression resistance were removed the voltage spike would rise to hundreds of volts (see the right side of figure 4) and arcing would occur across the switch contact. the light of the world hemingway https://purplewillowapothecary.com
