Two technicians are discussing electron flow. Tech A says that in conventional theory current is believed to flow from positive to negative. Tech B says that in electron theory current is believed to flow from negative to positive. Who is correct?

• Tech A

• Tech B

• Neither

• Both

With equal numbers of protons and ________, the charges within an atom cancel each other out, leaving the atom with no overall charge.

The __________ side of a circuit refers to the wires and components that originate at the positive post of the battery and end at either a switch or a load, whichever occurs first.

• Power

• Feed

• Ground

• Both A and B

A(n) ________ is used to measure the amount of resistance in a component or circuit.

• Ammeter

Technician A says when you ground a circuit, you hook it back to the positive side of the battery. Technician B says some manufactures use the chassis as a return path to the battery. Who is correct?

• Tech A

• Tech B

• Neither Technician

• Both Technicians

Tech A says that a voltage drop is typically used to find excessive resistance in a circuit. Tech B says that high resistance creates heat at the point of resistance in the circuit. Who is correct?
