How does a series circuit differ from a parallel circuit?

• A series circuit has components connected in a line, while a parallel circuit has components connected across common points

• A series circuit allows electricity to flow through multiple paths, while a parallel circuit flows through each component in turn

• A series circuit is always open, while a parallel circuit is always closed

• A series circuit uses static electricity, while a parallel circuit uses current electricity

What causes static electricity?

• The imbalance of electrons on a surface

• The continuous flow of electrons

• The attraction between electrons and protons

• The use of a power source in a circuit

What is the role of a switch in an electrical circuit?

• To open or close the circuit, controlling the flow of electricity

• To provide energy needed to move electrons

• To act as a load that uses electricity

• To prevent the flow of electricity

What is the difference between insulators and conductors?

• Insulators prevent the flow of electricity, while conductors allow it to pass through easily

• Insulators allow electricity to pass through easily, while conductors prevent it

• Insulators and conductors both prevent the flow of electricity

• Insulators and conductors both allow electricity to pass through easily

Categorize each of the materials as either a conductor or insulator.

Groups:

(a) Conductor

,

(b) Insulator

• Copper
• Paper
• Plastic
• Penny

• Iron nail

• Rubber
• Glass
• Aluminum

• Wood

• Gold

Categorize each as either Series or Parallel Circuit.

Groups:

(a) Series Circuit

,

(b) Parallel Circuit

• lights are all the same brightness

• Loads are arranged in a line

• Only one path for current to flow

• Lights will have varying brightness.

• Loads are parallel to each other

• Voltage is the same across all components

• 
• More reliable than series circuits

• 
• If one component breaks down, the whole circuit will burn out.

• 
• Multiple paths

•
