Ohm's Law
Learning Objectives
- Students will be able to apply Ohm's Law to solve circuit problems
- Students will be able to analyze I-V characteristics of components
- Students will be able to predict how circuits respond to changing voltage or resistance
Core Concepts
- V = IR relationship
- I-V characteristics
- Ohmic and non-ohmic behavior
Formulas
$$V = IR$$
Ohm's Law relating voltage, current, and resistance
$$I = \frac{V}{R}$$
Alternative form solving for current
$$R = \frac{V}{I}$$
Alternative form solving for resistance
Units
| Volt | V |
| Ampere | A |
| Ohm | Ω |
Interesting Fact
Ohm's Law is one of the most important relationships in electronics
Key Scientist
Georg Simon Ohm
Experimentally determined the relationship V = IR
Ancient Wisdom
The balance between voltage and resistance mirrors the concept of equilibrium and harmony found in traditional Chinese philosophy and Eastern spirituality.
