When paralleling a generating unit to a power system, if the synchroscope indicates that the incoming machine is running slower than the system:

a.  The field current should be increased

b.  The power input to the prime mover should be increased slightly

c.  The power input to the prime mover should be decreased slightly

d.  The synchronizing switch should be closed just after it indicates zero phase angle difference.

Among the following statements, which statement finds the logical consequence of the second law of thermodynamics?

1. This law states that the entropy of an isolated system always increases or equal to zero but can never decrease

2. This law is a relationship between the energy and the internal energy of a system

3. This law states that entropy attains a constant value at absolute zero temperature

4. This law states enthalpy of a closed system is a point function
