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 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.

Series circuits are simple & 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.
