Q11
The input resistance of the base of a voltage-divider biased transistor can be neglected
  • A at all times.
  • B only if the base current is much smaller than the current through R2 (the lower bias resistor).
  • C at no time.
  • D only if the base current is much larger than the current through R2 (the lower bias resistor).
Answer: Option B
