Session 3 basic electrical 4

What is 'ghost voltage' an indicator of?

• An open circuit

• 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

The sum of the voltage drops in a series circuit equals the __________________.

• amperage

• resistance

• source voltage

• wattage
