Five light bulbs are wired on one circuit. Three bulbs are lit, two are not. What type of circuit is this?
series circuit
parallel circuit
open circuit
short circuit
A good energy source for a simple circuit is
a battery.
a copper wire.
a light bulb.
a switch.
Which of these materials is a conductor?
rubber
chalk
gold
glass
What is one use for an insulator?
It slows down the flow of electric current to produce heat and light.
I 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 n the circuit.
the circuit contains a resistor.
the circuit has only one loop in it.
What will happen in a parallel circuit if one of its loops is broken?
electric current will not flow through any of the loops
electric current will still flow through the broken loop
electric current will still flow through the unbroken loops
the energy source will stop provideing the energy to move electric charges
A washing machine is an example of transforming
electricity into motion energy.
motion energy into electric energy
electricity into light
heat into motion energy
Which of the following is caused by the energy of motion?
resistor
friction
conductor
filament
One example of a resistor is
a power cord.
a parallel circuit.
a battery.
a filament.
Which of the following uses resistors to transform electricity into heat?
a toaster
a car engine
a gas stove
a wind turbine
This is a series circuit with a switch. Is this circuit open or closed? Will the bulb light up or not? (Look at the switch)
open circuit/bulb WILL light up
closed circuit/bulb WILL light up
open circuit/bulb will NOT light up
closed circuit/bulb will NOT light up
