DC Motor Speed Regulation A shunt DC motor Armature resistance is 1 ohm and field coil resistance is 100 ohms. Back emf constant is 9 volts for 100 RPM. The DC supply Voltage is 100 V and it is running with a speed 1000 RPM. What is DC supply current?

Of the three conductors, you used in this experiment (tubular resistor and two lamps) and based on your data analysis which are ohmic and which are not? Explain.

A. In the morning, the student plugs in a computer (240 W) to study physics, a microwave (800 W) to make breakfast, and a hair dryer (1200 W) to dry the hair. What is the overall current in this student's room, in Ampere?   B. A circuit in a student’s room has a 15 A circuit breaker. In the morning, the student plugs in a computer (240 W) to study physics, a microwave (800 W) to make breakfast, and a hair dryer (1200 W) to dry the hair. Will this be enough to trip the circuit breaker?     not enough information     no, because the overall current is more than 15 A     no, because the overall current is less than 15 A     yes, because the overall current is less than 15 A     yes, because the overall current is more than 15 A
