7th Grade #10: Information Technologies

If one bulb goes out in a series circuit, the remaining bulbs...

• also go out

• get brighter

• get dimmer

• explode, leaving shards of glass everywhere

If the switch was opened, what would happen?

• the ammeter would measure a current flowing

• current would no longer flow, so everything would be off

• the bulbs would stay on because they're connected to the cell

• the bulbs would burn out and catch fire

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.

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

• closed circuit
• series circuit
• parallel circuit
• open circuit

This is an example of a _______ circuit

• open

• series

• parallel

• switch

Pick the correct sentence.

• This circuit will work because it is a closed circuit.
• Energy will freely flow in this circuit.
• This circuit will not work because there is no energy source.
• This circuit will not work because there is no switch.

This is an example of a ______ circuit

• Series
• Parallel
• Open
• Dihexihedral

A _____ is sent through wires when you press down on a switch

• proton

• wave pulse

• neutron

• ampere

You have a 9 volt battery and want to triple the voltage. What would the voltage of the new battery be?
