General current flow in a transistor is from __________ to __________.
base, emitter |
|
collector, base |
|
base, collector |
|
collector, emitter |
The transistor is the foundation of modern electronic devices. It is made entirely from semiconductor material (making it a solid state device) and can serve many different functions in a circuit including acting as a switch, amplifier, or current regulator. A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor.
Which of the following is a characteristic of batteries connected in parallel?
the positive terminal of one battery is connected to the negative terminal of the next |
|
one connection is made between each adjacent battery |
|
total current equals the sum of the individual battery currents |
|
total current equals the average of the individual battery currents |
You can multiply the voltage or the current supplied by individual batteries by connecting them together either in series or in parallel. The characteristics of batteries connected in parallel are that total voltage equals the average of the individual battery voltages, total current equals the sum of the individual battery currents, the positive terminal of one battery is connected to the positive terminal of the next, the negative terminal of one battery is connected to the negative terminal of the next, and two connections are made between each adjacent battery.
Direct current flows from the __________ terminal of the voltage source to the __________ terminal.
negative, negative |
|
negative, positive |
|
positive, negative |
|
positive, positive |
Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.
Which of the following is a characteristic of batteries connected in series?
total voltage equals the sum of the individual battery voltages |
|
the positive terminal of one battery is connected to the positive terminal of the next |
|
two connections are made between each adjacent battery |

A solid state device has which of the following characteristics?
made from a mix of conductive and insulative material |
|
made entirely from insulative material |
|
made entirely from semiconductor material |
|
made entirely from conductive material |
