This circuit diagram represents a(n):
rectifier |
|
parallel circuit |
|
series circuit |
|
series-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.
Which of the following is not a purpose of a resistor in an electrical circuit?
limit the current in the circuit |
|
control the voltage in the circuit |
|
moderate the heat in the circuit |
|
multiply the current in the circuit |
Resistors can be chosen in a wide variety of values to control the voltage in a circuit, limit the current, or moderate the heat produced by the components in the circuit.
You would measure the amount of current through a circuit with a(n):
voltmeter |
|
ammeter |
|
potentiometer |
|
battery |
Current is the rate of flow of electrons per unit time and is measured in amperes (A). An ammeter is used to measure the electric current in a circuit.

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