📋 Key Facts Summary
- Charge equation: Q = I × t
- Current unit: amperes (A)
- Charge unit: coulombs (C)
- Electrons flow from negative to positive
- Conventional current flows from positive to negative
- Ammeter connected in series
- Current is the same throughout a series circuit
Quick Check: In which direction do electrons actually flow in a circuit — from positive to negative, or from negative to positive?
Electrons flow from negative to positive. Conventional current flows in the opposite direction (positive to negative) — this was the historical convention defined before the electron was discovered.
