Correct Answer : Option (D) : 0.6 T or less than 0.6 T
Explanation : Since μr for silicon steel is more than that of cast iron, flux density will be more than 0.6 T.
Correct Answer : all voltages and current
Explanation : KCL and KVL are valid for voltages and currents of all wave shapes during transient as well as steady state conductions.
Correct Answer : 22 Ω
Explaination :
Correct Answer : 360°
Explaination : Sum of phasors is maximum if they are in phase and 360° = 0.
