Water Current: Flow of water

Electric Current: Flow of charges

Does the amount of current flowing from the top of stream to the bottom of stream change?What about a in a wire?

The AMOUNT of current flowing into one end of the wire is the same flowing out.

Amperes: measure AMOUNT of currentSymbol: A

What is the device that measures Current?

Flow of charges

I Measured in:

Amperes

Remember …

: the device that measures the potential difference

Voltmeter

Current ( ) is measured in Amperes ( ).

Ammeter: the device that measure current in a circuit

Multimeter

What are some examples of a LOAD?

LOAD

Load: device that converts electrical energy into another form of energy

Ex: Light bulb, ________, _________

The Load and Resistance

How could you slow the flow of the current in a stream?

Dam puts resistance on the current

A Load resists the flow of current.

The Load and Resistance

Filament

Resistance: the amount that current that is slowed by the load
