CEDD LESSON 2| Electrical, Electronics and Logic Components P3

is an electronic component that is used to resist the flow of current flow of current and cause a reduction in potential.

It consists of a low conductive component joined by conducting wires at both ends.

When current flows through the transistor, the electrical energy is absorbed by the resistor and dissipated in the form of heat.

• True

• False

Answer explanation

Resistor not transistor

The resistor thus offers a resistance or opposition to the flow of current.

• True

• False

Each resistor consists of a 4 or 5 color band on its surface.

• True

• False

Each resistor consists of a 4 or 5 color band on its surface. The first three (two) colors represent the resistor value, whereas the 4th (third) color represents the multiplier value and the last one represents the tolerance

• True

• False

____________ resistors whose resistance value is fixed and are used to provide an opposition to the flow of current

can be metal film resistor which consists of small ceramic rod coated with metal or metal oxide, with the resistance value being controlled by the thickness of the coating.

can be a wire-wound resistor which consists of an alloy wrapped around a ceramic rod and insulated. They can be surface mount resistors which consists of resistive material like tin oxide deposited on a ceramic chip.

They provide a variation in their resistance value. They are generally used in voltage division.
