Fuses and Circuit Breakers | Open the circuit for safety reasons |
Short circuit | Current follows the path of least resistance |
Series circuit | Electricity follows one path...if one goes out, they all go out |
Parallel circuit | Electricity follows more than one path...your home |
Appliances | All appliances convert electrical energy into heat |
Simple Circuit | Four main parts = switch, voltage source, electrical device, and conductor |
