In a p- n junction diode not connected to any circuit,

Options

A. Potential is the same every where
B. The P-type side is at a higher potential than the N-type side
C. There is an electric field at the junction directed from the N-type side to the P-type side
D. There is an electric field at the junction directed from the P-type side to the N-type side

Answer

C

Explanation

In common emitter configuration of a transistor the input current is a base current input current
`i_(B)=(DeltaV_(B))/(R_(B))=(0.01)/(1000)=10^(-6)A`
Also current gain
`beta=(ic)/(i_(B))`
`:. i_(c)=betai_(B)=50xx10^(-5)A`
`=500xx10^(-6)A=500muA`
