Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?
integrated circuits |
|
series circuits |
|
series-parallel circuits |
|
parallel circuits |
Circuits containing transistors are packaged into integrated circuit chips that allow encapsulating complex circuit designs (CPU, memory, I/O) for easier integration into electronic devices and machines.
What is the voltage of most household electrical systems in the United States?
220V |
|
110V |
|
60Hz |
|
60V |
Most households use electricity with a voltage of 110V.
An engineer who wants to document an electric circuit would create which of the following?
a layout |
|
a schematic |
|
a matrix |
|
a blueprint |
A schematic is the proper name for a drawing of an electric or electronic circuit.
The volt is a unit of measurement for:
voltage |
|
power |
|
current |
|
capacitance |
Voltage (V) is the electrical potential difference between two points. Electrons will flow as current from areas of high potential (concentration of electrons) to areas of low potential. Voltage and current are directly proportional in that the higher the voltage applied to a conductor the higher the current that will result.
The farad is a unit of measurement for:
inductance |
|
energy |
|
power |
|
capacitance |
Capacitors store electricity and are used in circuits as temporary batteries. Capacitors are charged by DC current (AC current passes through a capacitor) and that stored charge can later be dissipated into the circuit as needed. Capacitors are often used to maintain power within a system when it is disconnected from its primary power source or to smooth out or filter voltage within a circuit.
