A short to ground
A short to power
A faulty meter
As the number of resistors decreases in a parallel circuit
Total resistance decreases
The current flow increases
The voltage-drop increases
Total resistance increases
If an insulated wire rubbed through a part of the insulation and the wire conductor touched the steel body of a vehicle, the type of failure would be called a(n) ________.
short-to-voltage
short-to-ground
open
chassis ground
If 200 amperes flow from the positive terminal of a battery and operate the starter motor, how many amperes will flow back to the negative terminal of the battery?
Cannot be determined
Zero
About one-half (about 100 amperes)
200 amperes
What would happen if a chosen wire gauge was too small (higher gauge) than required?
The fuse would "blow"
The wire would remain cool
The wire would become hot when the circuit is "off"
The wire would become hot when the circuit is "on"
During a starter cable voltage drop test, what is an acceptable voltage reading?
12.0 volts
0.3 volts
9.6 volts
1.5 volts
Kirchhoff's Law for current states
One Volt will push one Amp through one Watt
The current flowing into any junction of an electrical circuit is equal to the current flowing out
Low resistance loads will have a large voltage drop and increased current flow through each load
High resistance loads require more current to move through the loads
A component with a dashed outline around it indicates?
Only part of the component is shown
A grounded circuit
A component that is case grounded
A pointed ground point
A voltage drop test can be used to test for which of the following?
Open circuit voltage to a circuit
Excessive resistance in a circuit
The amount of current flowing in a circuit
Open circuit to other circuits

amperage
resistance
source voltage
wattage
