Consider the motor. If the resistance in the wire wrapping the rotor is 1, compute the energy
Question:
Consider the motor. If the resistance in the wire wrapping the rotor is 1Ω, compute the energy lost under the conditions described. What fraction of energy is lost to Joule heating in this situation?If the current is doubled but the rotation rate is kept fixed, how do the output power, Joule heating losses,and fraction of lost energy change?
