6. A switch is a device that:

Short circuits complex circuits
Holds a fuse
Has double polesOpens or completes a current path


7. When parallel resistors are of three different values, which has the greatest power loss?

The smallest resistance
The largest resistance
They have the same power loss.
Voltage and resistance values are needed.


8. The primary function of the bias circuit is to

hold the circuit stable at VCC
hold the circuit stable at vin
ensure proper gain is achieved
hold the circuit stable at the designed Q-point


9. A JFET

is a current-controlled device
has a low input resistance
is a voltage-controlled device
is always forward-biased


10. Often a common-collector will be the last stage before the load; the main function of this stage i

provide voltage gain
buffer the voltage amplifiers from the low-resistance load
provide phase inversion
provide a high-frequency path to improve the frequency response
