ELECTRICITY!
SERIES AND PARALLEL CIRCUITS
HOW MANY PATHS CAN CURRENT TAKE
IN A SERIES CIRCUIT?
HOW DOES A SERIES CIRCUIT DIFFER
FROM A PARALLEL CIRCUIT?
IN A SERIES CIRCUIT, THERE IS ONLY ONE
PATH FOR THE CURRENT TO TAKE. ALL THE
PARTS OF SERIES CIRCUIT ARE CONNECTED
ONE AFTER ANOTHER.
INEXPENSIVE TO DESIGN BUT HAVE
MAJOR DISADVANTAGES.
- IF ONE BULB BURNS OUT, THEY ALL
GO OUT!
- AS MORE BULBS ARE ADDED, THE
CURRENT DECREASES & THE BULBS
GET DIMMER.
WHEN BATTERIES ARE CONNECTED IN SERIES
THEIR VOLTAGES ARE ADDED TOGETHER!
PARALLEL CIRCUITS PROVIDE SEVERAL
PATHS FOR CURRENT TO TAKE.
WHEN BATTERIES ARE
JOINED IN PARALLEL, THE
VOLTAGE STAYS THE SAME.
WHEN BATTERIES ARE JOINED IN SERIES, THE
VOLTAGES ARE ADDED .
HOUSEHOLD CIRCUITS ARE PARALLEL
CIRCUITS.
