RESISTORS

Question 1

a two-terminal passive electronic component that controls the flow of
electrons.

Answer 1

RESISTOR

Question 2

is an electrical device that does not require an
external power source to perform its basic function in a circuit.

Answer 2

PASSIVE ELECTRONIC COMPONENT

Question 3

resistors are used to connect a pin to a high voltage (Vcc)

Answer 3

. Pullup resistors

Question 4

resistors connect a pin to ground (0V).

Answer 4

pulldown

Question 5

two basic types of resistors:

Answer 5

LINEAR AND NON-LINEAR

Question 6

Resistors are classified as fixed type
or variable resistors.

Answer 6

Linear

Question 7

are resistors that uses color code to mark
their resistance on their bodies. It can be a four, five or six color bands

Answer 7

Carbon composition resistors

Question 8

are constructed using a conductive wire and wound
on a non-conductive core. The resistances are marked on their body

Answer 8

Wire wound resistors

Question 9

are resistors with metallic film that is vacuum
deposited on an insulating substrate. The resistance depends on the
thickness of the film. The thicker the film, the higher the resistance.

Answer 9

Thick and thin film resistors

Question 10

are tiny rectangular ceramic body with
silver conductive edges on either end. It features the resistance value code
printed onto it, where there is space.

Answer 10

Surface Mounted Device resistors

Question 11

The values of these resistors can change through a dial, knob, and screw or
manually by a proper method. These include the sliding arm type. The arm is
connected to a shaft and resistance can be changed by moving the arm. Usually
used as volume control and tone control. These types of resistors are usually rated
according to its maximum resistance.

Answer 11

variable resistor

Question 12

are variable resistors used to change the voltage by
changing their resistance. This device is connected in parallel with the
output

Answer 12

Potentiometers

Question 13

change the current by varying their resistance, connected in
series.

Answer 13

Rheostats

Question 14

are variable resistors that is designed to be infrequently adjusted,
usually just at the point of manufacture or when the unit is being
recalibrated.

Answer 14

Trimmers

Question 15

are temperature-sensing devices which has large change in
resistance proportional to temperature.

Answer 15

Thermistors

Question 16

are designed to protect electrical circuits from excessive voltage surges
or transients. The resistance varies with changes in voltage

Answer 16

Varistors

Question 17

varies the resistance with changes in light.

Answer 17

Photoresistors
