Correct Answer : Option (C) : if line to line voltages are balanced or unbalanced
Explanation : Zero sequence component of line to line voltage is always zero irrespective of degree of unbalance.
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 :
