THEA 3130 Lecture Notes - Circuit Breaker, Series And Parallel Circuits, Direct Current
Document Summary
Aluminum, gold, copper, water our bodies are 60%, don"t get electrocuted. Direct current: usually lower voltage, electrons flow in one direction, most common example: a battery. Alternating current: a magnetic field induces current in a conductor as it passes through it, 2 big magnets coils rotate 60x per second, u ground connectors, twist lock connectors. Series circuits if one lamp breaks they all go out. Parallel circuits: if one goes out the rest just get a bit brighter from the extra electricity. Combination: if one breaks they all continue, but if you flip a switch all the lights go out. 60 hertz (electron cycles back and forth) Single phase (unless it"s a large motor) The water analogy the difference in water levels represents potential for flow measured in volts and in our case is constant at. The amount of water (electricity) flowing is measured in amperage (watts) and depends on the.
