Why would an electrician use parallel circuits to wire the lights in each room of a house instead of using a series circuit?
a.
when electricians get their license, they are only licensed to install parallel circuits. most electricians aren't certified to install series circuits.
b.
parallel circuits prevent electrons from flowing if part of the circuit is broken and therefore prevent fires. series circuits cause more fires because electrons still flow.
c.
electrons continue to flow in a parallel circuit even if part of the circuit is broken. in a series circuit, a break such as a burned out lightbulb would cause the current to stop in the whole room.
d.
parallel circuits are much easier to wire and are required by the electrical code for housing construction in most communities. series circuits are sometimes used with special approval.
