4.7kΩ and 4.7kΩ in series = 9.4kΩ
Worked answer for a 4.7kΩ and a 4.7kΩ resistor wired in series.
Equivalent resistance 9.4kΩ 4.7kΩ and 4.7kΩ in series
| Resistor 1 (R1) | 4.7kΩ |
| Resistor 2 (R2) | 4.7kΩ |
| Connection mode | series |
| Formula | R = R1 + R2 |
| Equivalent resistance | 9.4kΩ |
Resistors in series simply add up — the total is always the sum of the individual values.
