Study Notes
Chapter Three: Current Electricity
- Charges in motion constitute an electric current
- Lightning, a natural phenomenon, involves charge flow
- Many everyday devices (like torches and clocks) show steady current flow
- This chapter studies steady electric currents
3.2 Electric Current
- Imagine a small area perpendicular to charge flow
- Positive and negative charges can flow forward and backward
- q₁ is the net forward positive charge flow
- q₂ is the net forward negative charge flow
- Net charge flow (q) = q₁ - q₂
- q is proportional to time (t) for steady current
