series and parallel circuits/current & voltage

The movement of electrons from atom to atom in a line results in a flow of _____. 

• amperage.
• electric current.
• electromagnetic connectors. 

Resistance is

• Measured using an ammeter

• Units are 'volts'

• How difficult it is for electrons to move through an object

• The continuous movement of electrons in a wire

A conductor has _____ resistance. An insulator has ______ resistance.

• Low; high.

• Negative; positive.

• Positive, negative.

• High, low.

Define what a current is

• the flow of charge

• the speed of an electron

• the amount of charge

• the number of electrons

What is voltage?

• the sum of potential energy between two points in a circuit

• the speed of electrons as they flow around a circuit

• the difference in potential energy between two points in a circuit

• the opposition to the flow of current

The relationship between circuit components and energy is:

• circuit components REMOVE energy from the circuit

• circuit components ADD energy to the circuit

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 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.

This circuit does not work because…

• the bulbs are not connected properly
• the single cell is not powerful enough
• there is a break in the circuit
• there is a short crcuit

Current I₁ is ​ (a)   current I_2.

• equal to
• greater than
• less than
