A 240 V, 50Hz single phase supply feeds a SP-FC-FWR. The rectifier is used to power the armature of a separately excited DC motor. The DC motor ratings are 220 V, 10 A (armature current), 940 rpm, Ra= 1.750. What is the no-load speed of the motor?

A) What is a rectifier? B) What electronic component is used to filter the voltage at the rectifier output?

What is the purpose of the rectifier in ASK Demodulation?

In a DC machine, rectification process is carried out in order to get unidirectional output (DC). This rectification process is carried out by a) Half wave rectifier b) Full wave rectifier c) Mechanical rectification d) Centre tapped rectifier

A single phase full wave AC voltage controller supplies resistive load R = 10 2. The input supply voltage is 120 V, RMS at 60HZ. The controller is ON for 25 cycles and off for 75 cycles. Calculate: 1- RMS output voltage. 2- Input P.F.
