RESSISTANCE is the right answer as short circuit current
mainly depends on reactance i.e Inductance and
Capacitance .ressistance basically resposible for decay in
dc current and in short circuit case ac is very large.thus
ressistance can be neglected.

Answer / saurav

resistance

Answer / wareagle

Resistance and inductance are the most important values used
in the calculation. C is usually ignored.

Answer / guest

b)inductance

iii) A shunt motor runs at 70 rad/sec from a 460V supply and takes in an armature current of 100A. Resistors of 2.52 ohms and 1.64 ohms are connected in series with the armature and in parallel with the armature respectively. The field excitation remains direct from the 460V supply but the generated torque is halved. Determine the new running speed. Neglect brush voltage drop. The armature resistance is 0.4 ohms. [15]
