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.

 To determine input characteristics, the collector base voltage
VCB is kept constant at zero and base current IB is increased
from zero by increasing VBE.

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.
