8.5: Capacitor with a Dielectric

Initially, a capacitor with capacitance (C_0) when there is air between its plates is charged by a battery to voltage (V_0). When the capacitor is fully charged, the battery is disconnected.

Do you need high voltage or current to produce a spark?

Before the spark, there is no current at all, only a voltage (potential difference) between two points. Arc discharge happens when the voltage is high enough to overcome the gap, and then continues when conductors are drawn apart until the plasma dissipates. This depends on how large the gap is; you can easily draw visible sparks from a 12V power supply …
