The document discusses the CE configuration of transistors and its output characteristics. The CE configuration has the emitter grounded and acting as the common terminal for input and output, with the base as input and collector as output. To plot the output characteristics curve, the base current is held constant while the collector current is increased by raising the collector-emitter voltage, tracing out three distinct regions on the curve.

CE CONFIGURATION
 In this type of configuration, the current flowing out of the
transistor must be equal to the currents flowing into the
transistor as the emitter current.
 emitter is grounded and it is used as the common terminal for
both input and output. It is also called as grounded emitter
configuration. Base is used as a input terminal whereas
collector is the output terminal.

3. Output Characteristics
 It is defined as the characteristic curve drawn between output
voltage to output current whereas input current is constant.
 To determine output characteristics, the base current IB i s kept
constant at zero and collector current Ic is increased from zero
by increasing VCE.This is repeated for higher fixed values of
IB.

4. The output characteristic has 3 basic regions:
