This circuit component symbol represents a(n):
transformer |
|
capacitor |
|
AC source |
|
DC source |
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.
The joule is a unit of measurement for:
power |
|
resistance |
|
capacitance |
|
energy |
The joule is a unit of measurement for energy.
An engineer who wants to document an electric circuit would create which of the following?
a layout |
|
a matrix |
|
a schematic |
|
a blueprint |
A schematic is the proper name for a drawing of an electric or electronic circuit.
A transistor to an electronic circuit is like a _______________ to a house?
gate |
|
safe |
|
no trespassing sign |
|
driveway |
A transistor works by allowing a small amount of current applied at the base to control general current flow from collector to emitter through the transistor. A transistor acts as a gate or switch for electronic signals.
This circuit diagram represents a(n):
open circuit |
|
parallel circuit |
|
series-parallel circuit |
|
series 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.
