Which of the following statements about electrical resistance is true?
the more resistive the conductor is the slower electron flow will be |
|
the more resistive the conductor is the faster electron flow will be |
|
the less resistive the conductor is the slower electron flow will be |
|
electrically conductive materials have no resistive properties |
Resistance is opposition to the flow of current. As resistance increases, current decreases as resistance and current are inversely proportional.
A __________ electric current produces a magnetic field proportional to the amount of current flow.
moving |
|
high voltage |
|
stationary |
|
low voltage |
A moving electric current produces a magnetic field proportional to the amount of current flow. This magnetic field can be made stronger by winding the wire into a coil and further enhanced if done around an iron containing (ferrous) core.
Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?
integrated circuits |
|
series-parallel circuits |
|
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.
This circuit diagram represents a(n):
series circuit |
|
open circuit |
|
series-parallel circuit |
|
parallel circuit |
A series circuit has only one path for current to flow. In a series circuit, current (I) is the same throughout the circuit and is equal to the total voltage (V) applied to the circuit divided by the total resistance (R) of the loads in the circuit. The sum of the voltage drops across each resistor in the circuit will equal the total voltage applied to the circuit.
