Resistivity of Different Material & Colour Coding of Resistors
PHXII03:CURRENT ELECTRICITY

357518 Resistance of a carbon resistor determined from colour codes is \((22000 \pm 5 \%) \Omega\). The colour of third band must be:

1 Green
2 Orange
3 Yellow
4 Red
PHXII03:CURRENT ELECTRICITY

357519 A resistance is shown in the figure. Its value and tolerance are given respectively by
