Experiment
Quiz
1) If Rac is the resistance measured by applying AC voltage and Rdc is resistance measure by applying DC voltage. Then which one of the following is true.
Rac > Rdc
Rac < Rdc
Rac = Rdc
It depents on ac frequency.
2) As the slip increases, keeping all the parameters of the machine constant, the input current and the impedance
increase, increase
increases, decreases
decrease, decrease
decrease, increase
