In oder to read it, we need to know the colour identification. we just can simply check the resistors with multi-meter because that is easier than reading and calculating however by understand this identification, we can just realize the size of the resistor without multi-meter quickly.
| band colours | measured value | low tolerance | high tolerance | pass or fail | |
| red red black gold | 22.1 | 20.9 | 23.1 | pass | |
| blue grey yellow gold | 686k | 646k | 714k | pass | |
| brown red brown gold | 118.7 | 114 | 126 | pass | |
| green blue brown gold | 552 | 532 | 588 | pass | |
| orange orange brown gold | 326 | 313.5 | 346.5 | pass | |
| grey red black gold | 80.8 | 77.9 | 86.1 | pass |
all measurements are in Ohms units
to calculate total resistance in a series circuit, all you have to do is simply add the resistance within the circuit.
to calculate total resistance in a parallel circuit, you must follow the formula:
1/RT= 1/R1 + 1/R2
we put the 552ohms and 326ohms together in series circuit so that the total resistance is 552+326=879ohms.
And when the two resistors become parallel 1/552 + 1/326 = 1/total resistance which is 204.95
