Total Resistance vs Resistor 1
公式
Series Resistance
Resistors in series carry the same current, and their resistances add directly.
Formula
R_total = R1 + R2 + R3 + ...
The total resistance is always greater than the largest individual resistor.
计算示例
Three resistors in series: 100, 220, and 330 ohms.
- 01R_total = R1 + R2 + R3
- 02R_total = 100 + 220 + 330
- 03R_total = 650 Ω
常见问题
What happens to current in a series circuit?
Current is the same through every component. The total voltage divides across the resistors proportional to their resistance.
Why would you connect resistors in series?
To create a larger resistance value or to build a voltage divider circuit.
What if one resistor in a series circuit fails open?
The entire circuit breaks and no current flows, like a burnt-out bulb on old Christmas lights.
