A transistor amplifier circuit is biased so that the quiescent point is to the far left of the load line midpoint. What do you expect to occur when the input voltage begins to vary? O The output voltage will be distorted on the bottom because it will hit the lower limit for VCE before the input voltage arrives at its peak. The output voltage will be distorted on the top because it will hit the upper limit for VCE before the input voltage arrives at its peak. O The output voTransistor's output voltage will look like the input voltage amplified and inverted. The output voltage will be zero (flat).
