- 4. CODED VALUE OF RESISTOR
- 5. 1. First color band is green, table value: 5 2. Second color band is blue, table value: 6 Value after first and second color band: 56 3. Third color is yellow, table value (multiplier): 10KΩ 56 x 10KΩ = 560 KΩ 4. Fourth color is gold, indicating the tolerance (how much more/less can the actual resistance of the resistor can be used for): ±5% Decoding a Resistor Color Band
- 7. 1.To determine the lower range used: Lower Limit = coded value - the product of the coded value and tolerance 2. To determine the higher range used: Upper Limit = coded value + the product of the coded value and tolerance RESISTANCE RANGE
- 8. RESISTANCE IN SERIES CIRCUIT TOTAL RESISTANCE •R1 + R2 + R3
- 9. RESISTANCE IN PARALLEL CIRCUIT TOTAL RESISTANCE •1/R1 + 1/R2 + 1/R3 • If you only have two resistors of equal values, total resistance = half of resistor value •If you were to continue adding resistors, total resistance will drop due to its inverse relationship.
