Which of the following statements about electrical resistance is true?
the more resistive the conductor is the faster electron flow will be |
|
electrically conductive materials have no resistive properties |
|
the less resistive the conductor is the slower electron flow will be |
|
the more resistive the conductor is the slower electron flow will be |
Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
If an electrical circuit is interrupted, which of the following will result?
short circuit |
|
open circuit |
|
parallel circuit |
|
closed circuit |
A closed circuit is a complete loop or path that electricity follows. It consists of a source of voltage, a load, and connective conductors. If the circuit is interrupted, if a wire is disconnected or cut for example, it becomes an open circuit and no electricity will flow.
Electromotive force is another name for:
current |
|
power |
|
energy |
|
voltage |
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.
A diode to an electronic circuit is like a _______________ to a city?
traffic light |
|
one-way street |
|
parking lot |
|
highway |
A diode allows current to pass easily in one direction and blocks current in the other direction.
Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?
parallel circuits |
|
integrated circuits |
|
series-parallel circuits |
|
series 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.
