Parallel Series

The picture shows an electrical circuit. This circuit is a series circuit because: 

• It has 3 light bulbs.

• The same current flows through all three light bulbs.

• It uses a single battery.

• The electrical current is divided between the three light bulbs.

What kind of circuit is this?

• series

• parallel

This circuit has more than one loop. When one light goes out, the others stay on. 

• closed circuit

• series circuit

• parallel circuit

• open circuit

One of the advantages of _________ circuits is that they ensure all components in the circuit have the same voltage

as the source.For instance, all bulbs in a string of lights have the same brightness.

• open

• multiple

• series

• parallel

What will happen if one light bulb is removed from this circuit?

• The other bulbs will go out.

• The other bulbs will stay on

• The other bulbs will get dimmer.

• The battery will become stronger.

When you remove a bulb from a three bulb circuit, and the other two bulbs go off, then the bulbs must have been connected in __________.

• parallel

• series

• opened

• closed

all bulbs are lit equally the two top bulbs are brighter the single lower bulb is brighter the single bulb does not light and the other two are dim

• all bulbs are lit equally

• the two top bulbs are brighter

• the single lower bulb is brighter

• the single bulb does not light and the other two are dim

when the switch is closed.....

• both bulbs TURN ON

• both bulbs STAY ON

• both bulbs TURN OFF

• both bulbs STAY OFF

This type of circuit has multiple paths for the current to flow. If one component fails, the current can still flow through other paths.

• Series circuit

• Parallel circuit

• Open circuit

• Short circuit
