A transistor has hie =1KΩ and hfe=60 with an bypassed emitter resistor Re=1kΩ. What will be the input resistance and output resistance?

A transistor has hie =1KΩ and hfe=60 with an bypassed emitter resistor Re=1kΩ. What will be the input resistance and output resistance? Correct Answer 63kΩ and 40kΩ respectively

As the emitter is bypassed, the input resistance Ri=hie =1kΩ. The output resistance RO=1/hoe but the value is not given. So, hoe=0 and RO=1/0=∞.
