Elenco test

_______ operate at a much faster rate than their analogous counterparts

• mechanical components

• conducting components

• electronic components

• electrical components

When designing an electrical circuit, it is often necessary to use a _______ to _______ the amount of electrons or current that will move through that circuiteach second to prevent it from being damaged or destroyed

• calculator estimate

• formula amplify

• resistor limit

• resistor halve

electrons flow through materials when a potential pressure called _______ is placed on one end of the circuit

• Coulombs

• Voltage

• Valence

• Resistance

Some materials have a higher _______ that opposes the flow or current of electricity than the ones that allow electrons to move more easily

• rate

• voltage

• amperage

• resistance

_______ resistors can _______ their values when voltage is applied across them

• variable, change

• partial, only increase

• semiconductor, only decrease

• static, conserve

The type of "Through Hole" PCB resistors that are most popular for breadboarding are the _______ type.

• metal oxide

• metal film

• wire wound

• carbon film

When resistors fail (primarily due to out of spec over voltage) they may _______.

• burn or short out.

• sing and dance

• violently explode or flame out.

• shut off and reset

During the manufacturing process of the first generation of resistors, were manufactured first and then _______.

• tested to determine their values

• shipped to customers building radios

• tested in Eniac, the first digital computer

• dissassembled and fine tuned for later sorting

"Close enough" is usually good enough. Modern resistors can, at a high cost, be custom manufactured for any specific value. But since most electric components are somewhat forgiving meaning they can function properly while still being supplied a fraction more or less voltage than their ideal value (think the silver and gold tolerance bands painted on resistors) that over the years certain values became popularrather than making a special resistor of each concievable value. These values typically occur in _______% increments.

• 1 and 2

• 10 and 50

• 3 and 6

• 5 and 10

Capacitance is the ability of this component to accumulate _______ and _______ electrical charge until it reaches its capacity

• electrons, increase

• electrons, decrease

• holes, neutralize

• electrons, balance
