Parallel Circuits- Have MULTIPLE paths for electrons to travel.

Your house uses PARALLEL circuits.

Your car uses PARALLEL circuits.

Christmas lights are an example of SERIES circuits.

Is this a series circuit?

Will all of the lights turn off if one lightbulb breaks?

In a parallel circuit if one bulb goes out ALL bulbs go out.

In a series circuit if one bulb goes out ALL bulbs go out.

If you want all of your light bulbs in a series circuit to have the same brightness, what should you do? YOU SHOULD HAVE AN EQUAL NUMBER OF BATTERIES AS LIGHT BULBS

The equation for voltage is V=IR

Voltage is measured in VOLTS.

Current is measured in AMPS.

Resistance is measured in OHMS.

Current and voltage have a DIRECT relationship.

Current and voltage have a DIRECT relationship.

If you increase the current, voltage will INCREASE.

These are temporary magnets created when there's a CURRENT in a wire coil.

To increase the strength of our electromagnet we can INCREASE THE NUMBER OF COILS or INCREASE THE CURRENT

Motors convert ELECTRICAL energy into MECHANICAL energy.

Generators convert MECHANICAL energy into ELECTRICAL energy.
