A line voltage overload has _____ terminals to check.

• Two or three

• one

• four or five

• tewnty

To test a capacitor what setting should your multi-meter be set to?

• Continuity

• volts

• boats

• Resistance

With its leads on either side of a switch, a volt meter reads 120 volts. This indicates that:

• The switch is open, so voltage can not pass through

• The switch is open, allowing 120 volts to pass through

• The switch is closed, so voltage can not pass through

• The switch is closed, allowing 120 volts to pass through

• 5%

• 10%

• 20%

• 1%

The _____ must be placed in series with the load or circuit to read the amperage.

• dropmeter

• displacement meter

• in-line ammeter

• clamp on ammeter

• Resistance

• Installation

• Continuity

• Movement

The _____ is used to determine the operating condition of a component or a circuit.

• ohmmeter

• Lowest scale

• phase scale

• midrange scale

• Highest scale

The _____ is used to measure the amount of electromotive force available to a circuit or load.

• millimeter

• conduction meter
