Electric Current is the flow of electric charge:
- basic components of a circuit include power source, load/resistor (light bulbs, etc.), conductor and switch
- types of circuits include series, parallel, short circuits
- current flow in a circuit: alternating current (AC) and direct current (DC)
- voltage, current, and resistance are related: Ohm’s Law (V=IR)
- relative dangers of current and voltage
