What is a complete path through which electric charges can flow called?

• magnetic pole

• electric circuit 

• electric resistance

• magnetic field 

Irene bought a new house and has decided to rewire it. She wants to be able to turn some lights off and have the others remain lit. What type of circuits should she use and why?

• She should use parallel circuits because when one light turns off, the other lights remain lit.

• She should use series circuits because when one light turns off, the other lights remain lit.

• She should use parallel circuits because when one light turns off, the others turn off, too.

• She should use series circuits because when one light turns off, the others turn off, too.

Which switch, when opened, will make the light go out?

• Q

• R

• S

• T

Ronnie was building a circuit connecting battery to a light bulb to a battery. The current flows due to a difference in potential energy called ​ (a)   . The light bulb is a ​ (b)   , which slows the flow of current in the circuit.

• voltage

• resistor

• amperes

• circuit

A​ (a)   is a complete electrical path. An ​ (b)   is an electrical path that is not complete.

• closed circuit

• open circuit

• open current

• closed current

​ is the flow of electricity. The path the electrons take is a ​ . A ​ circuit has only one path for the electrons. A ​ circuit has more than one path for the electrons.

• current
