Review: Circuits

Which of the following is the symbol of resistor?

• 
• 
• 
• 

Which of the following is the symbol of a Power Supply or a Power Source?

• 
• 
• 
• 

How was voltage represented in the water analogy?

• an electric dam converting water to electricity

• the amount of water in a large container (e.g. water tower)

• the flow of water through the pipes

• turning a faucet on and off

How was current represented in the water analogy?

• an electric dam converting water to electricity

• the amount of water in a large container (e.g. water tower)

• the flow of water through the pipes

• turning a faucet on and off

An electrical circuit that is not complete and does not allow electricity to flow through it is called a __________________.

• simple circuit

• closed circuit

• open circuit

• parallel circuit

Electricity can only flow if the circuit is a/an _____________ loop.

• opened

• closed

• small

• large

Which of the following accurately describes the current of resistors in series?

• The current stays the same throughout the circuit

• The current through each resistor adds up to the total current of the circuit

• The current is 0 throughout the circuit

• Multiplying the current through each resistor is equal to the total current throughout the circuit

What is a series circuit?

• The transfer of electrons from one object to another
• A circuit with a single path the current follows
• A circuit that goes in multiple directions
• A circuit that takes place in a series of events

Why are resistors important in some circuits?

• Becuase they slow down the flow of electrons so the circuit doesn't over heat
• Because they protect against loss of charg
• Because they complete the circuit
• Because they control the flow of energy up and down

This picture is an example of what kind of circuit?

• Series
• Complete
• Parallel
• Broken
