When we apply reverse bias voltage to input and output sides of a BJT, then the width of the depletion layer at emitter-base and base-collection got increased. Due to which the effective base width got decreased. This phenomenon of reduction in the base width is called Early effect.
And if we go on increasing the Reverse bias voltage then at a time instant the width of the base becomes zero and this effect is called punch through effect and that reverse bias voltage is called punch through voltage.

What is early effect?
the early effect is a width base modulation due to which collector curren inc by inc of c-b voltage
Do boy have better gross motor or fine motor skills?
As children develop through early childhood boys have much better gross motor skills than girls, and vice versa. Boys are better at play involving throwing balls and physical rough housing, while girls are better at play involving using small objects (such as doll houses) and painting. They also gravitate toward these different types of play as they continue to develop through early childhood, further refining their skills.
When were electric lights invented?
Electrical lighting started in the late 1800s with the invention of the light bulb and the progression through carbon arc lamps. Electric lights became more common in the early 1900s.
What is base width modulation?
As the applied base-collector voltage (VBC) varies, the base-collector depletion region varies in size. This variation causes the gain of the device to change, since the gain is related to the width of the effective base region. This effect is often called the "Early Effect"An NPN bipolar transistor can be considered as two diodes connected anode to anode. In normal operation, the emitter-base junction is forward biased and the base-collector junction is reverse biased. In an npn-type transistor for example, electrons from the emitter wander (or "diffuse") into the base

The concept was first demonstrated by Sir Humphry Davy in the early 19th century
