Mo Valley Test 1-4 Study Set UPDATED ACTUAL Questions
and CORRECT Answers
A circuit is defined as a completed path for voltage to Fasle
flow from a source of voltage through a load and back to
the source.
T/F
A complete circuit or path is often referred to as a(n) closed
_____circuit.
Before current can flow in a circuit, the circuit must be True
closed.
T/F
Many non-electrical people often call an open circuit short
a(n) ______ circuit.
When current does not flow in a circuit, it is called a(n) ? open
circuit.
when a circuit is open, voltage does not exist in the False
circuit.
T/F.
when current finds an alternate path back to the source, short
rather than taking a path through the load, it is called a(n)
? circuit.
a short circuit causes a drastic decrease in the ? of the resistance/current flow
cirucit and could cause the ? to be dangerously high.
Ohm's Law states that it takes 1 amp to push 1 ohm of False
resistance through 1 volt.
T/F.
Current flow in an electrical circuit is caused by ? and voltage / resistance
opposed by ? .

For a given circuit, if the source voltage is increased, the True
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 decreased, the net False
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 the printing and use True
of small or large figures.
T/F
