The power source pushes a flow of electrons (current flow), measured in amps, when the switch is in the closed position, completing the path.

• True

• False

Technician A says an atom with more electrons than protons has an overall positive charge. Technician B says not all atoms can give up or accept electrons easily. Who is correct?

• Technician A

• Technician B

• Both Technicians A and B

• Neither Technician A nor B

'Energy' has the potential to:

• do work.

• infer work.

• store work.

• release work.

_____ are the amount of _____ moved.

• Amps; electrons

• Volts; electrons

• Amps; protons

• Volts; protons

Total circuit resistance is equal to the _____ of the individual resistances.

• Product

• Sum

• Remainder

• None of the above

Technician A says when the resistances in a parallel circuit are not equal, then the current divides in accordance with the value of each resistance, but the total current flow is still the sum of the currents flowing in each branch. Technician B says all components in a parallel circuit are connected directly to the same voltage supply. Who is correct?

• Technician A

• Technician B

• Both Technicians A and B

• Once; hollow

• Once; solid

• Many times; hollow

• Many times; solid

The primary coil typically has _____ turns of light-gauge wire and the secondary has approximately 20,000 to 30,000 turns of very fine wire.

• 50 to 100

• 100 to 200

• 200 to 300

• 400 to 500

Two technicians are discussing multiplexing and automotive networks. Technician A states that one such multiple system is a CANbus. Technician B states that networking is common on vehicles today reduce system cost, save weight, and improve reliability. Which technician is correct?

• Technician A

• Technician B

• Both Techs A and B

• Neither Technician A nor B

A good pair of wire strippers removes the insulation without damaging the wire strands.

• True

• False
