Correct Answer : Option (C) : four times
Explanation : Since diameter is doubled, area of cross-section becomes four times. Current carrying capacity is proportional to area of cross-section.
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.
