Which of the following allows encapsulating complex circuit designs for easier integration into electronic devices and machines?
parallel circuits |
|
integrated circuits |
|
series 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.
Which of the following is not a characteristic of a step-up transformer?
increases voltage |
|
the primary voltage is higher than the secondary voltage |
|
the secondary voltage is higher than the primary voltage |
|
has more turns in the secondary winding than in the primary winding |
As their names indicate, a step-up transformer is used to step up or increase voltage and a step-down transformer is used to step down or decrease voltage. In a step-up transformer, the secondary voltage is higher than the primary voltage and it has more turns in the secondary winding than in the primary winding.
This circuit component symbol represents a(n):
DC source |
|
AC source |
|
capacitor |
|
transformer |
Direct current flows in only one direction in a circuit, from the negative terminal of the voltage source to the positive. A common source of direct current (DC) is a battery.

power |
The hertz is a unit of measurement for frequency.
An engineer who wants to document an electric circuit would create which of the following?
a schematic |
|
a blueprint |
|
a layout |
|
a matrix |
A schematic is the proper name for a drawing of an electric or electronic circuit.
