The following data was obtained for a given transistor:

For the data, calcalate the input resistance of the given transistor.

Text Solution

Verified by Experts

Input resistance `=(DeltaV_(BE))/(DeltaI_(B))=(0.82-0.72)/((80-30)xx10^(-6))=(.10)/(50xx10^(-6))=(10xx10^(-2)xx10)/(50)`
`=(100000)/(50)=2000Omega`.
