|
110V |
|
60V |
|
220V |

Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?
series circuits |
|
integrated circuits |
|
parallel circuits |
|
series-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.
Capacitors connected in series produce __________ capacitance compared to capacitors connected in parallel.
more |
|
the same |
|
less |
|
no |
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.
A diode to an electronic circuit is like a _______________ to a city?
traffic light |
|
highway |
|
one-way street |
|
parking lot |
A diode allows current to pass easily in one direction and blocks current in the other direction.
This circuit diagram represents a(n):
series circuit |
|
parallel circuit |
|
series-parallel circuit |
|
open 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.
