Also, if an arc-suppression capacitor is used across the contacts, this capacitance will discharge itself through the relay contacts. The discharge surge current may be hundreds of amperes for a few nanoseconds or more. To limit such discharge currents, an arc-suppression capacitor should have a certain amount of resistance in series with it. In circuits where there is no dedicated
