Electric circuits

1st half

• Quiz about last week
  
• Dropping Marbles
• Questions on homework & making soms exercises

2nd half

• Demo & Game

Learning objectives

• In a circuit you can distinguish between the concepts of            Current, Voltage and Charge. 
  
  
• You can tell properties of current in a parallel circuit and a series circuit.

Which lamps shine brighter?

Why do the parallel lamps shine brighter?

Phet

1 lamp	0,9 A
2 lamps series	0,45 A
2 lamps parallel	1,8 A
1 battery	?current?
2 batteries series	?current?
2 batteries parallel	?current?

Ammeter & Voltmeter

If you close the switch,
how will the current flow?

1. Just through the lamp.
2. Only from battery to lamp.
3. All around the circuit, from + pole of the battery to the - pole.
4. All around the circuit, from - pole of the battery to the + pole.

Circuits: Quiz Questions!

Current

Charge

Voltage

Closing the circuit

Good conductor

Good insulator

Wrong text in book!  Cross out:

"The voltage of the power source determines how much energy the power source can deliver."  blz. 185,  end of middle paragraph

"Therefore , a socket can deliver more energy than a battery."

blz. 185, top of bottom paragraph

"The greater the voltage of the power source, the more energy the power source can deliver."  blz. 186, Summary
