- Students will be able to distinguish between conventional and electron flow
- Students will be able to measure current using an ammeter
Core Concepts
- Current as charge flow
- Conventional current
- Electron flow
Formulas
$$I = \frac{Q}{t}$$
Electric current as the amount of charge passing a point per unit time
Units
| Ampere | A |
Interesting Fact
In metals, electrons carry negative current; in solutions, both positive and negative ions can carry current
Key Scientist
André-Marie Ampère
Studied the relationships between current and magnetic effects
Ancient Wisdom
The flow of current mirrors the concept of life force or vital energy flowing through the body in traditional Chinese medicine and Ayurvedic traditions.
