Circuit breaker break the circuit when it sense any abnormal condition in the circuit using relay. Relay is a very important component in a circuit breaker.
Circuit breaker is a switch. Relay is a resettable protective device.
GOLD: 5% (tolerance)
SILVER: 10% (tolerance)
NO COLOUR: 20% (tolerance)
The first band gives the first digit.
The second band gives the second digit.
The third band indicates the number of zeros.
The fourth band is used to shows the tolerance (precision) of the resistor.
Short trick of colour bands:
