An engineer who wants to document an electric circuit would create which of the following?
a schematic |
|
a blueprint |
|
a matrix |
|
a layout |
A schematic is the proper name for a drawing of an electric or electronic circuit.
This circuit component symbol represents a(n):
diode |
|
fuse |
|
resistor |
|
capacitor |
Fuses are thin wires that melt when the current in a circuit exceeds a preset amount. They help prevent short circuits from damaging circuit components when an unusually large current is applied to the circuit, either through component failure or spikes in applied voltage.
This circuit diagram represents a(n):
rectifier |
|
series-parallel circuit |
|
parallel circuit |
|
series circuit |
In a parallel circuit, each load occupies a separate parallel path in the circuit and the input voltage is fully applied to each path. Unlike a series circuit where current (I) is the same at all points in the circuit, in a parallel circuit, voltage (V) is the same across each parallel branch of the circuit but current differs in each branch depending on the load (resistance) present.
Which of the following is not a characteristic of a step-up transformer?
increases voltage |
|
has more turns in the secondary winding than in the primary winding |
|
the secondary voltage is higher than the primary voltage |
|
the primary voltage is higher than the secondary voltage |
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.
A diode to an electronic circuit is like a _______________ to a city?
one-way street |
|
parking lot |
|
highway |
|
traffic light |
A diode allows current to pass easily in one direction and blocks current in the other direction.
