What are the three key elements needed for a basic electrical circuit to function properly? -
ANSWER 1. Electrical pressure or voltage
2. A conductor (something to transmit the energy)
3. A load (something to use the electrical energy)
pg 10
What is an open circuit? - ANSWER The inability of electrons to flow through a conductor and
provide power because the conductor does not provide a complete path.
pg 10
What is a short circuit? - ANSWER A circuit that does not have a load, or in which the load has
been bypassed.
pg 12
What is a fuse? - ANSWER An intentionally weakened point in a circuit that bursts open when
current flow is excessive.
pg 12
,Does a short circuit have very high or very low resistance? Does it have high or low amperage? -
ANSWER Very low resistance, very high amperage
pg 12
How many paths can current in a series circuit flow? - ANSWER One path.
pg 13
In a series circuit, because there is only one path for current flow, the current is the __________
at any point in the circuit? - ANSWER Same
pg 13
What is the example of a series circuit noted in the book (page 13)? - ANSWER Christmas tree
lights (street lights are also an example on page 14)
How many paths can current travel in a parallel circuit? - ANSWER Multiple paths.
pg 14
All power lines are what type of circuit type? - ANSWER Combination circuit type (A mix of
series and parallel)
pg 14
, Lineworkers should never place themselves in ___________ between two points of different
potential. - ANSWER series
pg 15
Anything that is connected in series will have current flow through it unless
__________________________________________? - ANSWER the resistance is sufficient to
prevent it.
pg 15
In a series circuit, if a certain amount of current is required for the circuit to operate properly,
what must be high enough to maintain the proper current flow? - ANSWER Voltage
pg 17
What is voltage drop and how does it function in a Series Circuit? - ANSWER Voltage drop is the
amount of voltage it takes to push a given current through a given amount of resistance.
In series, voltage will drop across each resistance connected to the circuit so less voltage is
available to push the current through the next load.
pg 19
The sum of all the voltage drops across all resisters must __________ the voltage applied to the
series circuit - ANSWER Equal
This means after the last resistor, all voltage on the line will be used up.
