Series Circuit
Learning Objectives
- Students will be able to analyze series circuits with multiple components
- Students will be able to calculate total resistance, current, and voltage drops
- Students will be able to predict behavior when components are added or removed
Core Concepts
- Series current
- Voltage division
- Total resistance
Formulas
$$R_{total} = R_1 + R_2 + R_3 + \cdots$$
Total resistance in a series circuit
$$I = \frac{V_{total}}{R_{total}}$$
Total current in a series circuit
$$V_1 = IR_1, \; V_2 = IR_2, \; \ldots$$
Voltage drop across each resistor
Units
| Ohm | Ω |
Interesting Fact
Series circuits demonstrate Kirchhoff's voltage law: the sum of voltages around a closed loop equals zero
Key Scientist
Gustav Robert Kirchhoff
Formulated Kirchhoff's Laws for circuit analysis
Ancient Wisdom
Linear ordering and sequence reflect concepts of dharma and cosmic order in Hindu philosophy — each element in its proper place.
