Journal Can the positive charges flow out of a battery to createelectricity? Why or why not? Use Pictures and Words. + Chemical Changes -
Current, Load, and Resistance Date: • Electric Current: the flow of charges • Symbol: I Water Current: Flow of water
Current Direction?
Current ???
Electrons • ________________ flow in ONE direction in a circuit.
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 current • Symbol: A
Electric Current: Flow of charges • Symbol: I • Measured in: Amperes What is the device that measures Current?
Remember … • : the device that measures the potential difference Voltmeter
Current ( ) is measured in Amperes ( ). Ammeter: the device that measure current in a circuit Multimeter
Source • Current
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
The Load and Resistance Filament
Resistance: the amount that current that is slowed by the load
