Circuits

In order for a circuit to work you need to have

• A voltage source
• A complete pathway with no breaks in the circuit
• A resistor
• A voltage source and a complete pathway with no breaks in the circuit

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

This type of circuit only has one path for current to flow. 

• series
• parallel
• combination
• split

This is an example of a _______ circuit

• open
• series
• parallel
