Q2. 2. A 220 V, 50 Hz ac voltage is applied  to  primary  side  of  10:1  stepdown transformer, which is used in bridge rectifier having load resistance of 1 KΩ. Calculate (i) peak, average & RMS value of load current (ii) dc output voltage (iii) dc output power (iv) PIV of each diode (v) efficiency (vi) output frequency. (Assume diodes to be ideal diode)

 

Answer 1

In common emitter configuration, base is the input terminal, collector is the output terminal and emitter is the common terminal for both input and output. That means the base terminal and common emitter terminal are known as input terminals whereas collector terminal and common emitter terminal are known as output terminals.

In common emitter configuration, the emitter terminal is grounded so the common emitter configuration is also known as grounded emitter configuration. Sometimes common emitter configuration is also referred to as CE configuration, common emitter amplifier, or CE amplifier. The common emitter (CE) configuration is the most widely used transistor configuration.
