Why are most schools wired in a parallel circuit rather that a series circuit?

Answer 1

So is your home. So are factories, offices, etc.In a parallel circuit, the voltage is predictable. All items are subject to the same voltage - in a serial circuit, on the other hand, the voltage even depends on OTHER elements in the same circuit, so that gets rather messy. Also, in a parallel circuit, you can turn individual consumers (e.g., lamps) on and off, independently from one another.

Answer 2

NO school, home, or office is wired as a series circuit. None.

-- A series circuit has only one path for current to follow.
So the current for EVERY device (every light bulb, radio, computer, printer, fan,
phone charger, air conditioner, coffee pot, blow dryer, stereo, night light, etc.)
must flow through ALL devices.

-- If any one single device in the circuit is removed, burns out, or is switched off,
(blow dryer, fan, etc.) then ALL devices in the circuit go off.

-- The power available to each device in a series circuit is determined by its own resistance
as a fraction of the sum of the resistances of all devices in the circuit. Sadly, the way it works
out is that the devices on a series circuit that need the most power get the least, and those that
need the least power get the most.

-- If one light bulb in a series circuit is replaced by a brighter one (take out a 60-watt bulb and
put in a 100-watt bulb), then the new bulb shines LESS brightly than the original one, but every
other device in the series circuit starts to dissipate MORE power than before.

There's more, but a series circuit is clearly NOT the way to distribute power

Answer 3

Schools use a parallel circuit because it allows for multiple devices to operate independently without affecting each other. In parallel circuits, each device gets the full voltage supply and can operate at its maximum efficiency. This setup also ensures that if one device fails, the others can continue to function.
