An engineer who wants to document an electric circuit would create which of the following?
a matrix |
|
a schematic |
|
a blueprint |
|
a layout |
A schematic is the proper name for a drawing of an electric or electronic circuit.
This circuit diagram represents a(n):
parallel circuit |
|
series circuit |
|
series-parallel circuit |
|
open 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.
Which of these materials is not a good conductor of electricity?
tin |
|
air |
|
copper |
|
gold |
All conductors have resistance and the amount of resistance varies with the element. In general, metals make the best conductors of electricity and non-metals make the worst conductors of electricity.
In a series circuit, which of the following is the same across all branches of the circuit?
voltage |
|
conductance |
|
resistance |
|
current |

Which of the following is not a purpose of a resistor in an electrical circuit?
control the voltage in the circuit |
|
limit the current in the circuit |
|
multiply the current in the circuit |
|
moderate the heat 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.
