  1. If the inductance and capacitance of a system are 1 H and 0·01 μF respectively and the instantaneous value of current interrupted is 10 amps. The value of shunt resistance across the breaker for critical damping is ________ kΩ
    1. 0.5
    2. 0.05
    3. 5
    4. 5.05
Correct Option: C

For critical damping,

R = 0.5 √
L
= 0.5√
1
= 5 kΩ
C0.01 × 10-6
