Study Notes
Electric Current
- The unit of current is the ampere (A), which is defined as one coulomb per second.
Current in Parallel Circuits
- In a parallel circuit, the current splits up between components in inverse proportion to their resistances.
Electrical Conduction
- In a metallic conductor, electrical conduction occurs when free electrons move freely within the metal, carrying electrical energy from one point to another.
Conventional Current Flow
- Conventional current flows from positive to negative in a circuit, opposite to the direction of electron flow.
Direct Current (d.c.) vs Alternating Current (a.c.)
- Direct current (d.c.) flows in one direction only, whereas alternating current (a.c.) periodically reverses direction, oscillating between positive and negative.
