A capacitor to an electronic circuit is like a _______________ to a house?
gate |
|
storage shed |
|
driveway |
|
safe |
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.
The valence shell of a semiconductor is how full of electrons?
less than half full |
|
half full |
|
empty |
|
more than half full |
Semiconductors have valence shells that are exacly half full and can conduct electricity under some conditions but not others. This property makes them useful for the control of electrical current.
Capacitors connected in series produce __________ capacitance compared to capacitors connected in parallel.
no |
|
more |
|
less |
|
the same |
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 connected in series produce less capacitance than capacitors connected in parallel.
An engineer who wants to document an electric circuit would create which of the following?
a schematic |
|
a layout |
|
a blueprint |
|
a matrix |
A schematic is the proper name for a drawing of an electric or electronic circuit.
Longer the electrical wires mean _______________ voltage drop.
diminishing |
|
greater |
|
lesser |
|
complete |
Electrical wires have a certain amount of resistance per foot. A longer wire means more resistance and a greater voltage drop.
