What will happen in a parallel circuit if one of its loops is broken?

• The energy source will stop providing energy to move electric charges

• electric current will still flow through the unbroken loops

• electric current will not flow through any loops of the loops

• electric current will still flow through the broken loops

A washing machine is an example of transforming

• motion energy into electric energy

• heat into motion energy

What is one use for an insulator?

• it slows down the flow of electric current to provide heat and light

• it stores electric energy for l

• it allows electric current to flow through it

• it makes electrically charged objects safe to handle
