A circuit is defined as a completed Fasle
path for voltage to flow from a source
of voltage through a load and back to
the source.
T/F
A complete circuit or path is often closed
referred to as a(n) _______ circuit.
,Before current can flow in a circuit, the True
circuit must be closed.
T/F
Many non-electrical people often call short
an open circuit a(n) _________ circuit.
When current does not flow in a open
circuit, it is called a(n) ? circuit.
when a circuit is open, voltage does False
not exist in the circuit.
T/F.
when current finds an alternate path short
back to the source, rather than taking
a path through the load, it is called
a(n) ? circuit.
a short circuit causes a drastic resistance/current flow
decrease in the ? of the cirucit and
could cause the ? to be dangerously
high.
Ohm's Law states that it takes 1 amp to False
push 1 ohm of resistance through 1
volt.
T/F.
Current flow in an electrical circuit is voltage / resistance
caused by ? and opposed by ? .

where I and R are known, and E is to
be determined?
a. I=ExR
b. E=I/R
c. R=E/I
d. E=IxR
,what mathematical equation is used d. I=E/R
where E and R are known, and I is to
be determined?
a. I=ExR
b. E=IxR
c. R=E/I
d. I=E/R
what mathematical equation is used d. R=E/I
where E and I are known, and R is to
be determined?
a. I=ExR
b. R=I/E
c. E=IxR
d. R=E/I
For a given circuit, if the source True
voltage is increased, the current
flowing through the resistance
increases by the same percent, and
thus is directly proportional.
T/F
For a given circuit, if the resistance is False
decreased, the net result will be a
decrease in current flow by the same
percent, and thus the current is
inversely related to the resistance in
the circuit.
T/F
prefix multipliers are used to simplify True
the printing and use of small or large
figures.
T/F

a. 1200 V
b. 12000 V
c. 120000 V
d. 1.2MV
The prefix for 1,000,000 is Mega or M. True
