If the inductance and capacitance of a power system are respectively ...
The voltage across the breaker contacts can be determined using the formula:
V = L * di/dt
1. Given values:
Inductance (L) = 1 H
Instantaneous current (di/dt) = 10 A
2. Substituting the values in the formula:
V = 1 * 10
3. Calculating the voltage:
V = 10 V
Therefore, the voltage across the breaker contacts is 10 V.
However, the given answer options are in kilovolts (kV), so we need to convert the voltage from volts to kilovolts.
1 kV = 1000 V
4. Converting voltage to kilovolts:
V = 10 V / 1000
V = 0.01 kV
Hence, the voltage across the breaker contacts is 0.01 kV, which does not match any of the given answer options.
Therefore, the given correct answer option is incorrect.
The correct answer cannot be determined with the given information.
