Length of collector is greater than that of emitter

(B) transistor consists of three regions: Emitter $(E)$,Base $(B)$,and Collector $(C)$.In terms of physical size,the Collector is made the largest to dissipate the heat generated during operation.The Base is made the thinnest to allow the majority of charge carriers to pass through it from the Emitter to the Collector.The Emitter is of moderate size,smaller than the Collector but larger than the Base.Therefore,the length (or size) of the Collector is greater than that of the Emitter.
