Identify the various types of register and find out the value from colour bands.

Color Bands

Resistor

Register are used to register the flow of current

Aur to control the voltage in a circuit. The amount of resistance that a register of fair is measured in ohms. Most register have coloured striped on the outside and this code will tell you it value of existence. You can use a multimeter for digital resistor colour code calculator to determine the value of a register.

Variable Resistor  ( potentiometer)

A variable resistor is also now as potentiometer. This component can be found in device such as a light demerger or value control for also. When you turn the shaft of a potentiometer the register change in the circuit.

Light Dependent resistor (LDR)

Allied depend register is also available register but is controlled by the light various turning a a knob. The resistance in the circuit change with the intensity of the light these are after found in exterior light that automatically turn on at dusk and off at down.

Band resistor colour code identification

Let us consider the colour code for the register with the band to the value 4 in the colour chart. Violet represent 7 and black represent the value zero brand represent the multiplayer  YELLOE, VIOLET, BLACK, BROWN,GREY. Yellow cross ponds10. Does the value of the resistance to the cross ponding colour code is 470 x 10 equals to 4700 ohm aur 4.7 kilo ohms with the tolerance band being grey which represent a tele range of plus minus 0.05%.
