Electric Current
Currents are the rate that electricity flows thru a wire
2 types of currents: Alternating Current (AC)
electricity flows back-n-forth like in a house
Direct Current (DC) electricity flows in one direction like in a battery
Circuits Closed Circuits
allow electricity to flow
Open Circuits have an opening in it and do not allow electricity to flow
Circuits 2 types: Series Circuit: one
path for electric flow
Parallel Circuit: several paths for electric flow
Parallel Circuit
Good for houses Operating multiple
loads Varying energy
needs (depends on what you plug in)
Safety
Fuses and Circuit Breakers: If there is too much
electricity going to one place, these automatically shut off the electricity
GFCI outlets: now required by law near any water source (circuit breaker)
