This circuit diagram represents a(n):
rectifier |
|
series circuit |
|
series-parallel circuit |
|
parallel 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.
You would measure the amount of voltage between two points in a circuit with a(n):
ammeter |
|
battery |
|
reostat |
|
voltmeter |
Voltage (V) is the electrical potential difference between two points. A voltmeter is used to measure the voltage between two points in a circuit.
An amplifier is most similar in function to which of the following:
capacitor |
|
transistor |
|
step-down transformer |
|
step-up transformer |
An amplifier is a device that takes a small input signal and creates a larger output signal. This makes it most similar to a step-up transformer which takes a smaller input voltage and creates a larger output voltage.
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 component symbol represents a(n):
DC source |
|
transistor |
|
AC source |
|
transformer |
In contrast to the constant one-way flow of direct current, alternating current changes direction many times each second. Electricity is delivered from power stations to customers as AC because it provides a more efficient way to transport electricity over long distances.
