Electrical Circuits
2
What is a series circuit?

• All parts of the circuit are connected.

3
How many paths are in a series circuit?

• Theres only one path for the current to flow
  through. When one bulb goes out, they all go out
  due to a break in the circuit.

4
What happens when additional resistors are added
to a series circuit?

• A resistor is another light bulb.
• The bulbs will get dimmer. The current must flow
  through more bulbs.
• Increase resistors decrease current

5
How do you measure the current in a circuit?

• Use an ammeter.

6
What are parallel circuits?

• The parts of a circuit are connected to different
  branches.

7
How many paths are in a parallel circuit?

• There are multiple paths. Its dependent on the
  number of branches.

8
What happens when you add branches to a parallel
circuit?

• More branches decrease resistance increase
  current
• This is because there are more paths for the
  current to flow through.

9
What instrument do you use to measure voltage?

• Volts (V) are the amount of energy in a circuit.
• To measure voltage, you use a voltmeter.

10
What do you k now about the circuits in your home?

• From the power plant to your home series
• To the rooms of your house parallel
• Within the rooms parallel and series
