Charlie writes the steps shown to describe the use of a
transistor in a closed circuit with flowing current.
Using a Transistor to Amplify a Signal
1. Current (14) flows from the base to the emitter.
2. An input causes a small increase in voltage across the
base and emitter.
3.7, increases a small amount.
4. Current (2) flowing from the emitter to the collector
changes a large amount.
Which change corrects the error in his steps?
A. Change the title to "Using a Transistor as a Switch."
B. Change step 1 to say that no current flows in the
transistor at the start.
C. Reverse the sizes of the changes in current in steps 3
and 4.
D. Reverse the direction of current in step 4.

An electron moves with a constant horizontal velocity of 3.0 × 106 m/s and no initial vertical velocity as it enters a deflector inside a tv tube. the electron strikes the screen after traveling 26 cm horizontally and 19 cm vertically upward with no horizontal acceleration. what is the constant vertical acceleration provided by the deflector? (the effects of gravity can be ignored.)
