Resistor Code Coding Chapter Test

In the five-band resistor color code, a blue fifth band indicates a tolrences if +-25%

True

A surfaces mount resistor that marked 100 has a resistences value of 100 ohms

False

If a 68K ohms resistor with a tolorences of +-10% measured 77.3k ohms it is barley within tolrences

False

The Physical size of a resistor is an indication of its resistance value

False

When silver is used in the multipler band, it indicates a fractional multipler of 0.1

False

A surfaces mont resistor that marked 5R6 has a resistances value of 5.6 Ohms

True

Gold in the multipler band indicates a fractional multipler of 0.1

True

If a carbon resistor has only three colored bands or stripes its tolerances is +-20%

True

In the Resistor color-coding scheme, gold or silver never appear in the first or second bands

True

In the four band resistor color code a silver fourth band indicates a tolerances of +-10%

True

In the four-band resistor color code, a gold fourth band indicates a tolerances of +-5%

True

Orange in the mulitpler band means muliply the first two ir three digits by 10 3 square

True

Resistor with five colored bands or stripes provide more precise resistance value

True

The Physical size of a resistor is an indication of its power rating

True

The main purpose of a resistor is to limit the current flow or to provide the desired drop in voltages

True
