What is one use of an insulator?
It slows down the flow of electric current to produce heat and light.
It stores electric energy for later use.
It allows electric current to flow through it.
It makes electrically charged objects safe to handle.
Electric current cannot flow in a series circuit if
the circuit contains an insulator.
there is a break in the circuit.
the circuit contains a resistor.
the circuit has only one loop in it.
