An engineer who wants to document an electric circuit would create which of the following?
a schematic |
|
a blueprint |
|
a matrix |
|
a layout |
A schematic is the proper name for a drawing of an electric or electronic circuit.
A solid state device has which of the following characteristics?
made entirely from insulative material |
|
made entirely from semiconductor material |
|
made from a mix of conductive and insulative material |
|
made entirely from conductive material |
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.
You would measure the amount of resistance at a certain point in a circuit with a(n):
ammeter |
|
potentiometer |
|
voltmeter |
|
ohmmeter |
Resistance is opposition to the flow of current and is measured in ohms (Ω). An ohmmeter is used to measure the amount of resistance at a certain point in a circuit.
What is the voltage of most household electrical systems in the United States?
60Hz |
|
220V |
|
60V |
|
110V |
Most households use electricity with a voltage of 110V.
| 240V 500A | |
| 120V 25A | |
| 60V 125A | |
| 12V 250A |
Connecting the 10 batteries in series multiplies their voltage while keeping their current the same yielding a 120V 25A configuration. Connecting the 10 batteries in parallel multiplies their current while keeping their voltage the same yielding a 12V 250A configuration. Using a series-parallel connection, 5 batteries can be connected in series and 5 can be connected in parallel resulting in a 60V 125A configuration.
