Correct Answer : Option (C) : temperature alarm circuit
Explanation : The resistance of a thermistor decreases with increases in temperature. It is used to monitor hot spot temperature of electric machines.
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.
