A connection to the frame of a piece of electronic equipment is sometimes referred to as ___ ground

• a chassis

• an earth

• a circuit

• either chassis or circuit

Which resistive component is designed to be temperature sensitive?

• Thermistor

• Rheostat

• Potentiometer

• Photoconductive cell

What type of switch is this?

• push button

• SPST

• DPDT

• SPDT

The negative and positive charge symbols are assigned (in that order) to the:

• proton and electron

• electron and proton

• atom and nucleus

• electron and element

A voltmeter is used

• to measure current

• in series with the circuit

• in parallel with the circuit

• to measure coulombs

If the current in a circuit equals 0 A, it is likely that the

• voltage is too high

• resistance is too low

• circuit has a short

• circuit is open
