ITE- Measurement & Circuits

Length can be measured in ________.

• meters

• inches

• light years

• all of these are correct

Convert 8 inches into centimeters.

• 30.48

• 20.32

• 8.00

• 15.24

A _______ is highly accurate when making linear measurements.

• vernier caliper

• steel rule

• micrometer

• protractor

The most accurate graduate size is ________.

• 64ths

• 32nds

• 16ths

• 8ths

The dial on a caliper makes one revolution for each _____ of an inch.

• millionth

• thousandth

• tenth

• hundredth

Most circuits have a ______ connected to two terminals

• 10 amp fuse

• GFCI

• LED

• load

If you add another light (resistor) to a parallel circuit:

• the current in the circuit goes down when you add another path

• the total resistance of the circuit stays the same

• the total resistance of the circuit goes up

• the total resistance of the circuit goes down

A fuse is used to:

• break the connection and save the device or environment

• add an additional path to the circuit

• increase the cost of a circuit

• monitors the amount of current flowing from the hot (small slot) to neutral (large slot)

In a parallel circuit, the current

• only takes one path

• has at least one point where the current divides

• takes only one path when there are other paths connected

• takes multiple paths called trees
