Part A
Electric Circuits
Paths for current to flow
Series Circuit: One path; current same everywhere
Parallel Circuit: Multiple paths; voltage same across branches
Must be a closed loop for current to flow
Electric Current
Flow of electric charge
Measured in amperes (A)
Higher current = more charge moving per second
Electrical Resistance
Opposition to the flow of current
Measured in ohms (Ω)
Depends on material, length, thickness, and temperature
Electric Power
Rate at which electrical energy is used or produced
P\=IVP = IVP\=IV
Measured in watts (W)
Ohm’s Law
Relationship between voltage, current, and resistance
Higher resistance → lower current (for same voltage)
