Description : Draw O/P characteristics of CB configuration and explain its working.

Last Answer : In common base configuration, emitter is the input terminal, collector is the output terminal and base terminal is connected as a common terminal for both input and output. The base-emitter ... In this region, a small collector current flows called leakage current when emitter current is zero.

Description : What difference between ELCB and CB ?

Last Answer : Any difference in both indicates the residual current which leaking to earth. ... An MCB(Miniature Circuit Breaker) is used to detect electrical devices and protect them from short circuit where as ELCB (Earth Leakage Circuit Breaker) is used to detect leakages with the intention to avoid shock
