Electrical2 midterm

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 Techs A and B

• Neither Technician A nor B

True or False. Volts, amps, and ohms are the three basic units of electrical measurement.

• True

• False

'Energy' has the potential to:

• do work

• infer work

• store work

• release work

____ are the amount of ____ moved.

(a)  

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

• Product

• Sum

• Remainder

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

• Neither Technician A nor B

The primary coil typically has (a)   turns of light-gauge wire and the secondary has approximately 30,000 to 60,000 turns of very fine wire.

Two technicians are discussing multiplexing and automotive networks. Technician A states that one such multiplex system is a CANbus. Technician B states that networking is common on vehicles today to 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
