Question

what is the resistance value of carbon resistor having 4 colour bands brown black yellow silver tolerance value?

Answer 1

Answer:There are many different types of Resistor available which can be used in both electrical and electronic circuits to control the flow of current or to produce a voltage drop in many different ways. But in order to do this the actual resistor needs to have some form of “resistive” or “resistance” value. Resistors are available in a range of different resistance values from fractions of an Ohm ( Ω ) to millions of Ohms.

Answer 2

Answer:

Calculating Resistor Values

For example, a resistor has the following coloured markings; Yellow Violet Red = 4 7 2 = 4 7 x 102 = 4700Ω or 4k7 Ohm. The fourth and fifth bands are used to determine the percentage tolerance of the resistor.

IT IS CORRECT YOU CAN VERIFY.
