The value of resistance used for resistance switching with the circuit breaker having high post-zero resistance is typicallya. R ≪ Lb. R2/L2 = (1/4LC)c. \(R < \frac{1}{2}\sqrt {\frac{L}{C}} \)d. \(R > \frac{1}{2}\sqrt {\frac{L}{C}} \)where L is the series inductance and C is the shunt capacitance at the circuit breaker contacts.
