Final answer:
The question asks for the dynamic response of a DC machine when a 100-volt supply is applied, but it's not possible to calculate the exact response without additional context and a defined mathematical model.
Step-by-step explanation:
The student is inquiring about the dynamic response in the time domain of a separately excited direct current (DC) machine when a 100-volt supply is applied to the armature. The values given include various parameters and constants for the DC machine and the load connected to it. Without a specific mathematical framework or equations provided in the question, it is not possible to generate an accurate dynamical response.
Normally, to provide a time-domain response, one would set up differential equations based on the electrical and mechanical equations governing DC motors considering the circuit elements (inductance and resistance values), and solve them using appropriate initial conditions. Then, if needed, the Laplace transform technique could be used to obtain the time-domain response of the system's current and speed or torque. However, this analysis requires more specific information and context that is not provided in the student's query.
