As you know,$$ as temperature changes so do BDC and VBE. For the purpose of this question, neglect the change in BDC and only consider the change in VBE.

If the transistor used, has a VBE of $0\mathrm{.}7$V at $25$C and VBE decreases $2\mathrm{.}5$mV with every degree change in temperature.$$ Find IE if the temperature$$ changes from $25$C to $100$C

Use the detailed method for IE

IE at $25$C$=$ Answer $5$ Question $1$mA

IE at $100$C$=$ Answer $6$ Question $1$mA
